Program works great. Very very few problems with it other than the crash on exit thing which is really no big deal.

One request is the ability to designate a Do Not Pass list on an per application basis. I'd like to be able to do something like the following

A, B, C, D, E being the instances of wow open with A as primary

1,2,3,4,5,6 all pass to all wow instances
7,8 only passes to A, B, C, D
9 only passes to A and E

I'm not sure if you can exclude the focused window but that is not really a big deal. Mainly the abliity to have keys not pass to certain wow instances would be nice.

And as always, window positioning and resizing....
