Can you move the view tool from brush panel to the left side panel and add feature to hold and drag with pencil to pan or zoom rotate. Zoom and pan with finger may cause screen fingerprint and stylus not work smooth. And feature with keyboard shortcut to do that is more better, thank you
For the UI button it’s not planned for now, you can see the reason below (especially since it would require lot of buttons):
Maybe in the future through customization though.
What I could do is reusing the smooth or sub button as camera modifier like zbrush http://docs.pixologic.com/user-guide/customizing-zbrush/navigation/
- Move – Alt+Click & drag Background
- Scale – Alt+Click, Release Alt, drag Background
Oh great, please add that in future updates. Thank you
