I use LibreOffice (mainly Calc) for personal spreadsheets and documents, but the UI is outdated. Worse than the look, I cannot use my familiar Excel keyboard shortcuts and instead have to learn new key combinations to improve my productivity (or use the mouse&#x2F;trackpad and learn to slow things down). Since my use is occasional, I get surprised many a times when weird stuff happens due to my muscle memory hitting something or doing some action expecting an Excel-like result. :)<p>I still like LibreOffice (Calc) and the fact that it&#x27;s actively developed. It&#x27;s not as bad as StarOffice&#x2F;OpenOffice was a long time ago, but at the same time it is a bit of a resource hog and startup times are a bit longer compared to MS Office.<p>I don&#x27;t want the ribbon interface to be added in LibreOffice. I just want a nice modern looking UI with nice fonts and support for older MS Office (2003 style) keyboard shortcuts.<p>(The newer MS Office keyboard shortcuts after the advent of the ribbon are horrendous. Every new version loses some more older, quicker shortcuts.)
