I’m quoting my own first post here.
I did see you add the SubD (now pink) button, I hoped you continued and complete this… but I just read wim’s comment about “When it ships, the Rhino 9 UI will look like it does now.”
Currently SubD AND Meshes have only the “tool” button+toolbar, but they both do not have a button+toolbar for primitives!
Also, SubD button seems “lost” and far away from other 3d construction button.
Watch again my image ^ and compare it with current Rhino 9/WIP clean install or after a _Reset:
And NO access to any other SubD primitives.
Mesh: 2 buttons “Creation” and Tools" each with its own dedicated toolbar.
SubD: 2 buttons “Creation” and Tools" each with its own dedicated toolbar.
2 pink buttons + 2 acquamarine buttons just under the pink ones.
Please! 
Thanks!
Fresh install or after _Reset:
- left buttons are in a 4 columns style
- osnap and filter mutually excluding each-other in a whack-a-mole game with tabs (how to make new users quit before learning… do this!)
… Simply: NOPE 
Instead, do:
- 2 columns of buttoms.
- osnap and filter on bottom side-by-side as a single line.
That’s the only reasonable way.
