Sketchbox

it's cool program for sketch for diagram or use  case, but for me is USELESS because i'm left-handed. it is not possible that in 2020 a VR program where you draw must necessarily use your right hand, this thing is offensive towards left-handed people.

I used Sketchbox for the first time today and it was exactly what I needed. It's very intuitive to use, and you can completely focus on the work, without any distractions from your surroundings. 
I even caught myself wondering what else I could visualize, just because I now have a great tool for that.
