Thanks for the R,H,Z keyboard shortcuts, I didn’t know about these. I tried it already and this feature is good but I know I’ll be having a hard time getting used to this one since I need to look at my keyboard for the RHZ keys.
Also as for my pen buttons, I already assigned Middle Mouse Click and Right Click, which I find easier for me.
Holding the spacebar in combination with the pen buttons would be great to have. I’m used to this one since maybe I use Maya every day that I’m already used with the Alt (instead of Spacebar) + Pen Buttons for Rotate, Pan and Zoom.
