I have got a lot of buttons on my cyborg mouse. (R.A.T 7)
Basically, what I want is to use those buttons to do the stuff I can do when holding SHIFT or CTRL.

So please add a controls config to NSMBe.

I'm not sure if/how these buttons are exposed to the app via the winforms api.

Anyway adding configurable controls in the editor is a VERY bad idea in my opinion, for multiple reasons:

1. There WILL be users that screw up their controls without knowing what they're doing and then come crying that the editor doesn't work. It's not very user friendly.

2. Now in tutorials we can no longer say "control click this and drag" but we'll have to say "do whatever you have configured in the controls, could be control click or something else"

What could be done is hard-code certain extra buttons to do something useful, dunno how to go about this because lots of these mouses are different and I don't have any of them...

Ok then leave the current controls config alone.
People should be forced to keep the primary buttons (because of the reasons you pointed out). But people should also be able to add secondary buttons to the config.
(So we can actually use any button we want and keep the original ones too)
