Changing names with Expert mode enabled

[Woodstock]

I would argue that naming of the files is a basic feature, not an expert feature.

I would agree with you. However... fixing that would be the author's job. I would actually suggest dropping calling it "Expert mode" and making it the default (or just make Expert "on" when installed), but... I have to be careful, because I've had it turned on "forever", so I forget some things that do not appear with it off.
