Suggestion: option for enable-control-button to left bar hand side (for the righties)

[SiameseParrots]

Toggling add/Substract works like charm. Love it and also the approach for other solution - enabling control.

Its a good sweet spot for the left hander, as using the right thumb for toggling while sketching on the blueprint with the left hand (I believe you are left handed as far as I remember)

Having an option in the settings to mirror the button position somewhere to the far left for the right handers. Thats the only thing missing imo.

rrly nifty update!
