My new DLL DCX (which is still in dev) has native rclick support for toolbar buttons and much more possibilities than what MDX has to offer in terms of those kind of things.
http://dcx.scriptsdb.org/dcx.htm <-- you can read the help files on controls already made and functionnal and see how it will work.
And it will also have button text color possibilities like mIRC's switchbar buttons (same thing will apply on treeview items having independant colors and probably listview too)
anyways, the DLL is in dev for the moment, I will probably hand out a beta later this month if you are interested to test ité.
For the moment it only works with XP (there's a bug that makes it crash in 98 and since I don't have any 98 OS here, it's quite hard to tell what happens)
