I have had a surprising amount of Scoundrels asking me about how to make a one button function to manage their attacks and heals, so I decided to just throw this up there. Click the link, read over the README and have fun smashing that F1 button to 75.
edit: This thing isn't exactly user friendly for everyone. I didn't really want to bother figuring out where exactly each skill comes in at in the skill trees so there aren't any checks for what your skill levels are in guile, improvisation and gunslinging and by default it assumes you have all the main bashing skills. The README explains how to edit things to what you want to use but if it confuses you, just comment here and I'll do what I can to try and help.
