Oh, oh, so you just've decided this moment to stay?!
Let's give Petko the chance to annouce good things for version 6, then (, or not), before taking any decision!
But you're right, I've got Prof., and I hadn't been aware of this feature before your post, and it's great.
Petko, do NOT hide it in the export menu (in which you probably hid it because of its probable belonging to the Prof. features?) anymore, but take the effort to put it both into the file menu and the shortkeys list, even if you have to split up those for Standard and Prof. for this. Logically, export is exporting to OTHER programs, not for shifting within MI itself, so nobody looks it up there, and making to find such a fine feature by accident only is not wise, marketing-wise.
(This also applies a "Done" to my post "do a function 'save this subtree as new topic'" elsewhere in this forum.)
