1. I have been using CC3 and IC3 from the beginning an orbiting the camera still gets stuck when orbiting, and it's very annoying, please fix.

2. Personally, I use a lot of Maya and so the hot keys don't really affect me, but some customs are coming from other DCC's like 3DSMax or Blender. It would be great to switch the default keyboard short cuts to help them out.

3. While cosmetic (I understand Reallusion does this for branding), it would great to change the Razer lime green accents in CC4 and IC4 to user defined colors. It will allow me to personalize the interface, as I spend a lot of time there, and that lime green gets very boring.

It's already in place and can be switched in Preferences > Control (implemented in one of the latest releases).
I am extremely pleased I could switch it to Blender 2.8 mode - the one I got used to most.
