Perspective Grid improvements

Question

The new Perspective Grid feature is pretty nice... at first.
But it quickly becomes almost useless as modifying the Grid after Objects are constrained to it does not re-orient the objects.
What's the point? So if we get the Perspective Grid set up, add objects, and if it turns out the Perspective needs to be tweaked... you can't?
It might actually be nicer to have a per-object-based Perspective Tool that does re-transform the object if you move the grid.
And then you could have more than one grid.
Or maybe you could make it so that the Free Transform Tool doesn't redraw the bounding box every time you make a change.

Answer 1

Thanks, that's what I was looking for. Though I have to admit it took me a half hour to get it to work.
And it's still clunky to work with. I don't think I'll be using it much.
And I haven't been able to summon that dialog you show. I've tried double clicking everything with either Grid tool selected. I'm just not seeing it.
Thank you, anyway. I wouldn't dare using the Perpective Tool without this feature.
About the Free Transform Tool:
What I meant was I'd like to be able to freely distort any object or group in order to make a faux perspective.
When you select an object and summon the Free Transform tool you can stretch any corner independent from the other corners using a secret keyboard shortcut which I can't remember anymore. I hate how so many functions are hidden behind secret keyboard presses in order to make something work.
Actually, I just found it in my notes. With the Free Transform Tool you have to start moving a corner, then, and only after you started to drag you can press the Command (or Control) and then you can stretch that point. I made a sample below. I should have made it into a group of objects so it was clearer what was happening.
Anyway, imagine this: say you have a simple rectangle. With the Direct Selection Tool you can move any corner without disturbing the other 3. That's what I'm looking for. I'd like to do that with any object or group. The problem is when you use the Direct Selection Tool to do it, the Bounding Box resets after every move. If you distort it too much, the corner points in the bounding box quickly become harder to use because they are so distant from the "corner" of the object which they are controlling.
In Corel DRAW it's so amazing simple rather than the clunky steps I have to go through to do it in Illustrator (as in the video).
