[Feature Request] Support for mouse buttons remapping

[iarwain]

Hi,

At the moment, it seems all actions linked to mouse buttons (left/middle/right) cannot be remapped, such as contextual menu or view panning.

Being able to remap those actions and access additional mouse buttons (thumb/side buttons, etc...) would be great.

Additionally, users relying on a trackpad don't always have a middle button option, which remapping would allow them to circumvent.

I'm super late to replying to this; I apologize! Yes, being able to remap keybindings to mouse buttons would be good (particularly for people who want to, say, pan with the right mouse button). I'll add this feature into the next version of MasterPlan (which is currently undergoing a rather large rewrite, v0.8.0). Thanks for the suggestion!
