Don't get me wrong, I think Solvespace is really important and I am glad you are keeping it ticking over, but it is the least fun UI I have ever encountered, I'm afraid (kind of obtuse on a trackpad too)
Not saying any of this is easy — Shapr3D on an iPad, expensive and marketed on its extraordinary usability, is just utterly perplexing!

Oh, I actually hate trying to use solvespace with anything other than a 3-button mouse. Unfortunate because the web version can actually run on my phone but is unusable in practice.
