Hi! first of all, great plugin!!
i have a suggestion: is it possible to have an "aplly" button in the plugin interface? i mean, sometimes is good to play around with the settings, and when you hit "ok", if you want to play a little more, you have to go all the way down again and set everything again.....so, i think an aplly button will help a lot, because it wont close the plugin window, so you can change the settings and aplly them again in the same window!
anyway, this is a very useful script, thanks a lot!
