I'm actually quite surprised that so few seem to use a keyprofiler kind of addon, and that I can only find just this one addon for keybinding profiles. I use this with BindPad, which doesn't have a profile system (and won't, I guess).
What I'd love to see is an updated version of KeyProfiler (or a new addon entirely) that would
1) have a support for LDB displays instead of Fubar
2) know how to update your current profile instead of always creating a new one
3) maybe a way to make a keybind to switch different profiles (this just came to my mind, don't know if it's possible now i.g. with a macro)
KeyProfilers libs also aren't properly managed since eventhough the addon folder contains Tablet-2.0, the library isn't loading if it's not loaded as an external addon. (Cannot find a library instance of Tablet-2.0)
