I don’t mind the interface so much - it could be improved of course.
What bothers me much more is the usage of the horrible, old, buggy and outdated ‘Windows Forms’.
Every a bit more complex panel (e.g. Material editor) redraws like its 1996.
And with windows 10 we cant even change the white background of panels anymore.
While programming rhino plugins it actually was sometimes the reason for bottlenecks: while the opengl part was doing fine, some realtime ui panel updates slowed down the whole system.
I understand that reworking this is a huge project, but it should have been done already 10 years ago…
The way it looks now, rhino7 will have the same 20 year old ui tech running…
