Please include proper support for tablet users. As of now the only thing I can do with my pen in the viewport is rotate it. Dragging using mid-button doesn't work - and using QE + AWSD hotkeys for zooming/panning is slow and frustrating. Please add support for mid-button dragging with a pen - and please add a way to quickly zoom using a pen as well. I suggest adding an option to zoom in/out by holding the right-mouse button and moving it up for zoom in and down for zoom out - or a key + mouse combo like in 3ds max.
Dragging works in the Graph view, but I have no good way of zooming in/out. Right now I use the wheel on my Wacom tablet, but this is not ideal. Hotkeys for zooming in/out would be nice here (maybe the same hotkeys for zooming in/out in the viewport - keep it simple?).
Dragging up/down in the left and right Toolbox/Properties panels doesn't work. This is clearly designed for people with a scroll wheel. I suggest enabling mid-mouse button hold drag (across the app - everywhere), so I'm not forced to hunt the small scroll bar all the time.
Hotkey customization would also be nice.
My specs:
Windows 10 Pro + 1.2.1.3 Pro + Wacom Intuos 4
