LibreOffice (aka LO) is among the best and the most used free (of cost) and open source office suites. The just-announced, brand new version 4.4 boasts some new features and a much needed design overhaul.\nA bit of history\nTalking about design, I must say that has been the number one complaint of LibreOffice users (the second being it's absence on mobile devices). LibreOffice still shows remnants of the design from the \u201890s.\nOne may wonder why?\nItalo Vignoli, one of the co-founders of TDF, once told me that when they forked OpenOffice, which was acquired by Oracle through Sun Microsystem, they inherited a lot of junk code piled up inside OpenOffice.\nWhen I asked about the \u2018state' of the junk code, Italo Vignoli told me \u201cI would not define OOo source code as junk, even if we all know that it was in dire need of a rejuvenation. If we look at translation of German comments, 90% is gone and 10% has yet to go (but of course is the 10% most difficult to find inside the source code). We can probably use the 90\/10 split as a good indicator of the general situation versus legacy OOo source code that needed rejuvenation."\nThe primary objective of the developers was to clean up that code to improve compatibility with Microsoft Office and polish its design. You don't start ripping out and replacing the wallpaper in an old house; you first take care of the foundation and make it stable before getting into cosmetics. That's exactly what LO teams have been doing so far.\nVignoli dives into the biggest challenges for the LO teams, \u201cInteroperability is the most challenging activity, and is eating the majority of developers time, together with new feature development and improvement of source code quality. With LibreOffice being deployed by an increasing number of organizations, interoperability is not limited to other office suites but also to enterprise solutions generating documents based on legacy file formats such as RTF, or very old DOC or XLS files. Of course, many of the larger deployments are contracting LibreOffice certified developers for this task, and the benefit is shared with the entire ecosystem (as all patches are pushed to master, once they have been tested).\u201d\nIt's changing\nWith the 4.4 release, it looks like the developers have cleaned up the code enough to deal with the design of the product. The new LibreOffice not only shows a sleeker toolbar, it has also added a side panel; similar to the one found of IBM Lotus Notes which also inspired Calligra Suite by the KDE community.\nI found the sidebar to be more space efficient than the bulky Ribbon UI developed by Microsoft for their office suite - the Ribbon takes up over 50% of the screen space. A sidebar makes more sense on modern widescreen monitors where the horizontal space gets wasted.\n \nLibreOffice 4.4 features a brand new design.\n\nIn LibreOffice 4.4, the sidebar is enabled by default, but you can enable or disable from the 'Views' option. What's even better is that you can disable the main toolbar to save more space. Go to 'Views > Toolbars >' and uncheck the 'Standard\u2019 and \u2018Formatting' options.\nIf you are running a Mac, you must certainly try LibreOffice to see the polish of the new design. Chances are you would never touch Pages again; either way you should not use Pages for any serious work if you don\u2019t want to lose your work.\nBut the question arises: is that a modern look and feel for an Office Suite in 2015? Vignoli agrees and says, \u201cFirst of all, we should agree on the concept of "modern look and feel".\nMicrosoft has almost managed to convince every user that the Ribbon is modern and ergonomic, but the reality is that it is not ergonomic. We have been working extensively on the user interface of LibreOffice 4.4, and the results are showing even if the look and feel has not changed. Thanks to this effort, the size of the design team has increased and this will be further reflected in the future.\u201d\nHe believes that the Android version of LibreOffice will help in improving the overall look and feel of the office suite. He says, \u201cThe user interface on mobile devices has to fight with space, and this is a compelling reason for creative solutions.\u201d\nUnder the hood\nIn addition to the UI improvements there is a lot of work done on improving the code base. Some of the major improvements in LO 4.4 include support of OpenGL transitions in Windows, and improved implementation based on the new OpenGL framework. You can now sign PDF documents when you export a document as a PDF file.\nIn a recent interview Vignoli told me about the tactics Microsoft uses to break compatibility with competitors. And one of the tactics was to use proprietary fonts as defaults. LibreOffice is now trying to tackle that tactic by offering free fonts Carlito and Caladea to replace proprietary Microsoft C-Fonts Calibri and Cambria.\nTalking about the compatibility issues when I talked to Vignoli today he said, \u201cEvery Microsoft Office document comes from a different version of the same pseudo-standard format. Of course, this makes it difficult to handle the entire spectrum of potential issues.\u201d\n\u201cWe run a roundtrip compatibility test on thousands of documents (save the file with Microsoft Office, open it with LibreOffice, save it with LibreOffice in the Microsoft Office format, open it back with Microsoft Office to verify that the file is not only readable but identical), but this is still not enough to get to 100% interoperability (although we are down to a small number of corner cases),\u201d he added.\nAnother issue that I faced with my editor at ITworld was: I use LibreOffice and Microsoft's track changes were breaking everything in LO (and even in Google Docs).\nVignoli explained, \u201cTrack Changes are handled in a completely different way on ODF and OOXML (to the point that Microsoft is still not supporting them in ODF) and this is probably one of the reasons why they are not always handled as intended. Here we are going back to the fact that there should be only one document standard, but you know the story\u2026\u201d\nI am not certain when, and if, track changes compatibility will improve between LO and Microsoft Office. What I do know is that with this release LO is working on improving track changes \u2013 with new buttons in the Track Changes toolbar \u2013 and AutoCorrect features in Writer.\nOther areas of improvement include: improved import filters for Microsoft Visio, Microsoft Publisher and AbiWord files, and Microsoft Works spreadsheets. The new version also comes with new import filters for Adobe Pagemaker, MacDraw, MacDraw II and RagTime for Mac.\nGrab it now\nLibreOffice is available across platforms - Linux, Mac OS X and Windows; there is a LibreOffice Viewer for Android.\nYou can get the latest version from the download page of LibreOffice. If you are using any Ubuntu-based distro, add the LibreOffice Pre-release PPA to your system and upgrade it. If you are running openSUSE, then Tumbleweed already has 4.4.\nSo what are you waiting for?Go ahead install it and never look back at expensive and closed source office suites.\nLibrate\u00a0your documents!
