From <https://www.zdnet.com/home-and-office/work-life/5-stand-out-libreoffice-features-that-make-it-my-go-to-office-suite/>: Customizable GUI: For example, when writing a novel, I want the sidebar always readily available because I need quick access to formatting options. If I'm working on a more traditional document, I might go with the tabbed UI. For spreadsheets, I want the simplest UI that I can use, such as the contextual single UI. LibreOffice makes this possible, with the ability to switch between a standard toolbar, tabbed, single toolbar, sidebar, tabbed compact, groupedbar compact, and contextual single. You can even make changes to different tools, which allows you to have one UI for Writer, one for Calc, and one for Presents. Customizable styles: What I like about this feature is that it allows me to get very granular with the styles, even to the point where I can define what style comes next, how drop caps are handled, transparency, borders, indents & spacing, text flow, font, position, highlights, much more. No AI: (what more needs to be said?) Microsoft Office compatibility: For a while, I was writing everything in Google Docs; that is, until one of my editors complained of incompatibility issues (even when exporting to the .docx format with Docs). Once I switched from Google Docs to LibreOffice (for my fiction writing), those issues all went away. Document export: LibreOffice document export allows you to export your Writer documents to XHTML, PDF, EPUB, MediaWiki, Writer Indexing Export XML, JPEG, Writer Layout XML, PNG, and WEBP. You can also save as ODF, ODF Template, Flat XML, Unified Office Format, Word 2010-365, Word 2007, Word 2007 Template, Word 2003 XML, Rich Text, Word 97-2003, and other types. If there's a format you need, more than likely LibreOffice can export it. ... I can also ask what version of MS Office a collaborator is using and make sure to export it to the most compatible version. Because, you know, even Microsoft Office cannot manage 100% compatibility with Microsoft Office ...
