@CmykStudent @Polychrome okay so, i think it's both actually
3.0 feels like it's trying to be an UI/UX remake, like Blender's restyling around 2.8, which is bound to draw some complaints but be better in the long run
but it instead ends up feeling like a poorly reskinned 2.10 to me, things don't feel better, they just feel slightly.. off, while also working a bit worse
basically, it changed too much without actually changing at all, if that makes sense?

there's also some weird issues which may or may not be on the GTK side, like the cursor disappearing over slider controls i mentioned i think elsewhere in the thread
also opening settings sometimes crashes the whole thing, which i'll actually need to report at some point if i don't forget (i probably will, my memory is terrible)

my personal suggestion would be to make it a long-term goal to rethink the UI/UX from the ground up, similar to what was done with Blender; it will piss off some long-time users in the short term, but also likely will make the whole thing more accessible to new users
