I would like to clarify how the user from the tablet will be more convenient to zoom, holding the right mouse button or with a combination of Alt + Rmb can also?
I think Maya navigation which is like the universal controls could work, this also leaves the RMB free for Right Click Menu and the other click functions free on the viewport. This navigation mode works on mouse and tablet the same way
ALT+MMB = PAN
ALT + RMB = ZOOM IN/ZOOM OUT
ALT + LCLICK = ROTATE/ORBIT
F = Zoom Extents
Honestly, we are more focused on the control style of the blender.
We have already made an alternate version of the zoom, we will assign ALT + RMB as the keys of the alternate version. After the appearance of settings most likely will make it possible to change the control, but for now so.
Thank you for your reply, I did not know if I can write you an email.
