Good video, very much worth watching despite the length. New UI will look something like this:
with an option for a more classic look.
Looks like an enourmous UX improvement too, and a rewrite to QT and eliminating a lot of technical debt will make development faster.
I actually like FreeCAD and its UI a lot and the recent improvements are huge! Yes it has its quirks but for a tool as versatile as FreeCAD they are acceptable.
It's definitely improving! I hope they also improve the default shortcuts because having to reach to almost the last key on the other side of the keyboard (k) for the single most used constraint is pretty nuts while there are almost unused closer keys lol.
