I don't think I am your target audience, but I will respond just so you have at least one data-point.
I don't use gestures. Ever. For anything (except unlocking my phone, which I am stuck with).
Opera 'introduced' mouse-gestures a long time ago, and like all other attempts I have tried; I cannot understand the point. I don't think that waving my hand/mouse/fingers around like a spell-caster writing runes in the air is ever efficient. There is far too many chances at misinterpretation, and it obscures the target action. Give me buttons. on/off-yes/no simple binary choices that give exact feedback.
Need something more analog (i.e. volume slider) let me input a number.
