1. You can do easily with events
2. You can do relatively easily with events (I think this is in the FAQ, and maybe the explosion too)
3. That would be nice, but you can fake it pretty well ATM.
4. This is practically impossible. Flash is dying anyway.
5. Could be useful, I guess... However I think you can actually do it with events by comparing the mouse X and Y.
6. If you use dt properly, this should work fine...
7. I find copying events easy... what do you mean?
Just my thoughts ;)
