That's the real beauty of MoI. You can operate it entirely with a single mouse button without ever touching the keyboard, or you can go all-in with shortcuts. The fact that shortcuts can also run scripts makes it incredibly powerful.

As for Modo, I feel that at some point, they started adding features to the UI mainly to satisfy their existing customer base (and perhaps the shoe industry) without much thought for potential new users.

I do agree with you KENMO, heavily based addons software like Blender are always a nightmare to keep up to date, new release break things, Blender dev's dont really care (and they shouldn't imho). It was already the case with 3dsmax, even if usually there was a 2y cycles before going full break.

That said in the little poly modelling landscape, I still think Blender is the wise choice if you start from scartch. Not the easiest to learn, but on the long run it will pay off. There is so much content for it now too.
