I’ve connected a Bluetooth mouse to my Ipad and it works really well
Have also tried to work in shapr3d with the mouse as a complement to the pen and I was surprised how easy and smooth it is, it feels absolutely right!
Please, you can make it zoom in and out with the scroll function it would be a huge upgrade !!
and yes I’m left handed (holding the pen with my left and the mouse with the right hand)
it is truly fantastic!
