the UI still feels a little last-decade
Oh good.
Ribbon: Garbage
Fisher Price version XP: Horrid, much easier on eyes switched to Win98/Win2K/NT4.0 style
Vista Aero & Transparency: TERRIBLE. Though you can turn it off and make it like Win98/Win2K/NT4.0/XP style
Win7: Stupid flat creeping in, basically a Vista Service Pack
NT4.0 -> Win2K -> XP ->Vista/Win7 -> Win8 -> Win10: Increasingly inconsistent GUI, and Explorer behaviour and splintering of where things found.
Switched permanently to Linux Mint + Mate Desktop (effects off) TraditionalOK theme about 2 years
Switched permanently to LibreOffice about 3 years ago (I'd used Star office and Open Office occasionally, but mostly MS Word & MS Excel since 1993)
So now left the insanity. Wiping remaining Win10 + MS Office shortly.
So called Modern GUI design is GARBAGE simulation of monochrome laser printed paper designed by Graphic designers that seem to know NOTHING about GUI research from 1970s to 1990s. It's gone downhill since 2003 with either insanely flat monochrome or drug addled hyper realistic 3D animations, AKA eyecandy.
The GUI is NOT a piece of art or a Graphic Design statement. It's has to be simple, consistent, work with mouse & keyboard (Stylus & Touch are specific use areas, not a replacement for text / figure / navigation creation). It must not distract or require study.
