I don't feel like we really need that where we == I :).
Seriously, I didn't even had a look at your code but if possible, it'd
be cooler if you would realise this as a plugin. This way you can
implement like you want and you are not dependent on the opinion of us
picky devs :).
Maybe you will run into problems following mouse events for
GeanyEditors from a plugin. If so, just tell us, maybe we can extend
the plugin API. But as I said, I didn't look at the code at all.

Enrico
