TL;DR: I wish they'd just align with Blender on UX, TBH.

I wish they settled on a nicer UX with less visual clutter. I use Blender and it is a _massively_ more complex application in every regard, yet its right-aligned panel and progressive exposure of toolbars feels infinitely more polished than FreeCad's clunky panel (which is often rendered with huge, oversized fields and buttons) and their legendary five-stacked toolbars.

Feels like that satirical Gillette ad, and is much harder to use and navigate, especially since quite a few UX options need to be turned on in Preferences to be usable...
