Great concept, but I will suggest that innovating on types of clicks (left + right, left + scroll wheel, etc.) is a mistake that will inhibit adoption of your app.

Your personal fingers might work well that way, but there is a reason those combinations are "unused" and "available" for your app. Countless other devs over the years have all concluded "yeah, that doesn't actually work for most people's hands." I don't have specific examples, but lots of early 3D modeling apps (possibly including early blender?) used weird combo clicks. The industry learned from that mistake and newer tools use more conventional hotkeys.

You've built something very cool and useful. It will be much more successful if you don't try to innovate in an unrelated area. Just use normal hotkeys, and let people customize them in case the ones you default to don't work for them.
