Hello there,
I had an idea for StrokeIt (a thoroughly useful utility, by the way!)...
How about a priority setting for each gesture? For example, 'C' in the default closes the current window. I wanted to set 'C' for K-Meleon as close layer but even if you set 'C' in the K-Meleon group, it performs the close window, not layer.
How about about being able to set a priority for a gesture in a sub-menu so that 'C' means something in most applications but is over-ridden in those where it is set specifically. You'd probably want to warn a user they are over-riding some other behaviour when they're setting it, though.
Hope this is as useful as your tool is to me! :)
Richard.
