Operators are one of the last places in Blender to use older UI designs
that don't fit in with recent style conventions. Updates for consistency
and clarity can greatly improve the experience here.
- Alembic import export UI
- Collada import export UI
- USD Export UI
- Bevel operator
- Blend from shape operator
- Object convert operator
- Screenshot operator
- Mixdown operator
- New image operator
Although the diffs look very messy these are very simple, purely visual changes.
So I would propose this change for 2.90. Along with the other updates to UI
this would fit right in (in my opinion).
