Hmmm, maybe you should try with a bar switching mod... sprocket is for mouse navigation. ;)
What is sprocket but a really nifty bar mod though? I don't see any reason to leave this kind of binding functionality out if it's not extremely difficult to do so. It would be great for minimalist UI users like myself who could go without showing any bars on their screen and just pressing a few buttons to see and switch between bars.
I have 2 suggestions, I only skimmed the post, so sorry if these were mentioned. =X
1) Allow for range coloring.
2) Allow bindings to individual menu buttons. I don't mean buttons to toggle the menus like you already have, but assigning each button a number (12 o clock is 1, 10 o clock is 8 ) that carry over all menus. For example, when opening menu 1, if I bind a button to 12 o clock, that same binding works on menu 2.
The point of those changes is that I think sprocket could become a very interesting bar mod. It would leave your screen very clean, and pop up with exactly what data you need when you needed it. It would be truly revolutionary.
