And a nice video on how to make the tool interaction:

Why not, might be useful. Although, I'm not sure how to integrate it to the transform tool. I mean it already has 2 different modes so 2 different types of interaction. I wouldn't want to add one more.
Unless there is some way to integrate this "perspective correction" function nicely to the free transform mode.. ?

That could work...

I kind of agree... I would even think that spliting the two modes of the transform tools in two different tools would be better. But then, yes the perspective correction would integrate with the second mod.

Implemented by now.
