I have noticed that you have updated the SubD toolbar, arranged much better!
I would like to highlight just one small thing: unfortunately, after the service release, the icon of the “SubD Revolution” tool was not added.
(also, in Italian, you should correct the term “REvoluzione” in “RIvoluzione”, this is correct).
Another small flaw found in the SubD toolbars:
Inside the “SubD Toroid” tool (passing the mouse arrow), the item “merge all coplanar faces” appears (right mouse button). This entry should be deleted!
The SubD toolbar has finally been better organized (it was all confusing before).
You should just add an icon of the “revolution” command, I don’t understand why, after so many Service Releases it is still not present (only this one is missing).
Also, the icon for this new SubD command has been added: “PackSubDFaces”. I would like to say that this icon is really ugly put together with the others: those jarring, fluorescent colors have nothing to do with the typical (cute) Rhino icons!
I would advise you to modify it, making it more in line with the other icons: even the eye wants its part!
