> I don't like the new MS UI.
It was introduced 8 years ago. It is hardly new anymore.
While going to the ribbon 8 years ago was a struggle, I couldn't go back now. The context aware parts, realtime previews, and just organisation is too good.
Unfortunately LibreOffice now feels cluttered and overly busy by comparison. That's more because Libre/Open Office has stood still, largely based on Office 9x rather than trying anything new themselves.
I'm not saying they should copy everything Microsoft does. I am saying that they should evolve themselves and look at where the industry is headed. For example look at all of the UI concepts from the web and touch devices, they've introduced a number of new ideas none of which Libre/Open Office have adopted.
If I wanted to use LibreOffice on my Surface Pro, I couldn't, no touch UI at all. That's a little disappointing.
