Well, I'm happy to agree to disagree here ;-)

I personally am sometimes confused since it's often unclear in MoI if hitting a button is going to the next stage of a multi-stage command (like in your example with the object selection) or if hitting it will actually apply the result. When selecting objects, "Done" makes absolute sense. But in the case of filleting, when I'm on the last screen, the missing differentiation between "Done" as in going to the next screen and "Done" as in applying the fillet finally is a bit too generic for me.
I understand and respect what you try to achieve, it just doesn't work for me personally.

But no big deal - I just wanted to bring it up for discussion. There's always Undo ;-)

I look forward to whatever improvements you decide to implement.

Cheers,

Tom
