Homeworking and the Role of Open Software in 2022


As most will agree, it’s been an unusual two years as the Covid pandemic has transformed society and ushered in new approaches and attitudes to the way we work, such as homeworking.

Impact of the Pandemic and Homeworking

In this blog we talk to Michael Meeks, General Manager of Collabora Productivity, to get his take on the business impact of the pandemic, the rise in homeworking and the ongoing pressure on organisations to enable and support effective distributed team collaboration and secure data sharing.

Discussing how the pandemic directly impacted Collabora Online, Michael explained that Collabora had always been a very virtual business so homeworking was nothing new.

“We utilise the skills and expertise of people from around the world, so distributed working is a necessity for us. Similarly, from a sales perspective, the pandemic, fortunately, has not been disruptive as it has for many other businesses. In fact, our sales over the last two years have increased significantly, which is possibly a direct result of organisations needing to respond to homeworking.”

Michael explained that they’d seen a growing number of businesses turning to Collabora Online as a way of solving urgent operational gaps brought about by the closure of offices.

“For many organisations, simply extending office-based solutions into the homes of their staff was either too expensive or technically too difficult.”

Tried and Tested Collaboration Solution

Collabora Online presented a tried and tested alternative to the commonly used office document solutions. Not only did it offer a familiar ‘desktop’ look and feel, which is important when trying to maintain productivity levels, but it was easy to deploy within a web/browser-based distributed environment, so it answered many of the issues business decision makers were asking when extending the working environment into a less-controllable domestic setting.

Michael said:

“We regularly talked with decision makers who recognised the urgency of homeworking, but were, understandably, concerned about operational implications, such as productivity, data security and legislative compliance.” He continued: “Given the way Collabora Online is built on the LibraOffice common core, we could provide a feature-rich, distributed office document collaboration solution that was tried and tested, and already optimised for the demands of the homeworking environment.”

Throughout the pandemic, and beyond, Collabora Online was, and is, being used by serious, tech-savvy organisations that need a document collaboration solution that not only provides more control over every aspect of its operation, such as the servers and networking it is hosted on, but greater security over the, often sensitive, data exchanged and stored in office documents.

Collabora Online, Office Productivity Market and Open Software in 2022

So as we move towards greater levels of ‘normality’ what does 2022 look like for Collabora Online, the office productivity market and open software in general?

“I think homeworking is here to stay,” suggested Michael.

“This long-term transition has clearly been accelerated by the pandemic, but you could argue that as the search continued for a better work/life balance, it would have come about sooner or later. As such, more and more organisations will be looking for solutions, such as Collabora Online, that are already optimised for a distributed working environment. Homeworking can come with its own challenges, especially when problems arise. In these circumstances, businesses need to be confident they can quickly and easily get the support they need, when they need it, which they can from us at Collabora.”

With regards to the open software market, Michael was very positive:

“Open Source software is everywhere now and is dominant in new product development, and although a tension can occur with commercial drivers that sometimes encourage bad practices, such as a reluctance to contribute back to the overall open software community, most of those involved get it and understand the huge benefits working with Open Source can deliver”

So 2022 looks like an exciting year for Collabora Online as it continues to respond to the evolving needs of a distributed, increasingly security-aware market, with end users keen to protect their flexibility and avoid getting tied to one dominant supplier.

Collabora Office 6.4 Released

Cambridge, August 4th, 2020 – Today we release Collabora Office 6.4 providing businesses and professionals with the best features, interoperability, LTS and custom support in open source while respecting user privacy and company data security. Changes in Collabora Office 6.4 also support new and enhanced features in Collabora Online.

Excellent Interoperability and World Class Support

Collabora Office 6.4 offers excellent interoperability with all major office formats. Import text documents, spreadsheets and presentations from MS Office files or the Open Document Format and save them just as easily. We maintain the world’s largest team of certified LibreOffice developers and offer our customers a long-term supported version of LibreOffice. Version branch 6.4 of Collabora Office will be supported until August 2023 at least.

New Features in Version 6.4

In addition to improving performance and interoperability, Collabora Office 6.4 brings a number of practical improvements to your work. The newly implemented functions can be found all over the suite. The following are some outstanding examples.

 

Adding Visible Signatures to Existing PDF Files

Collabora Office already had the capability to add a digital signature to an existing PDF file. This still works the same. That signature however is (and was) only visible on the status bar and in file properties; there is no visible signature in the PDF file. Now in Collabora Office 6.4 adding a visible signature has been made possible. You start this new feature by selecting the PDF file with File > Digital Signatures > Sign existing PDF.

Ad visible signatures to existing PDF files

Read all details in this blog post.

 

Send Encrypted PDF Files with Mail Merge

One of the very handy and well established features of Collabora Office Writer, is Mail Merge that directly sends out PDF files. In version 6.4 this function has been extended so that you now can send encrypted PDF files. This enhances the privacy options of your workflow. Find more details in our blog.

 

Encrypt your PDF when sending them with Mail Merge

 

Padded Numbering Up to 5 Characters

Padded Numbering allows you to work with list numbering using a prefix. This is now possible up to four zeros. The feature that was introduced in an earlier version was limited to prefixes of two zeros.

Set Distance of Shapes to the Bottom of the Page

It can be very handy to specify the vertical position of a shape in text documents by setting the distance at the bottom of the page content area. Until now, this was not possible, although you can do so with the distance at the top of the page content area. If you tried to do the same from the bottom, the shape would be pushed below the margin. Collabora Office 6.4 now fixes this. You can set a negative value for the position to the bottom of the page content area, and the shape will stay in that position. Also when for example the page size is changed, or when other content is added or moved. More details are described in this blog.

 

 

Export Larger Pages from Draw using PDF 1.6

Using PDF 1.6, exported PDFs can now be larger than 508 cm (200 inch). Before the size was limited because of the possibilities of the PDF 1.5 specification. Since PDF files from Collabora Office, or more specifically from Draw, can be used to create banners, a limitation of 5 meters only is of course, impractical. More background on this can be found in this blog.

Semi-transparent Text in Writer

Collabora Office 6.4 supports semi-transparent text, as it is also supported by Microsoft Word for DOCX files. So this again represents an interoperability improvement. In this blog you can find more details.

Upstream LibreOffice and more…

Collabora Office is based on the stable LibreOffice branch with extra features and fixes. Collabora Office 6.4 has the capabilities as described in the LibreOffice 6.4 release notes, of which quite some, especially these for our customers, have been introduced in earlier versions of Collabora Office. Of the 6.4 features, quite some have been added by our Collabora Productivity team. As an outstanding example, we feature the Full PDF Export for Spreadsheets.
