Allow 3D, 2D view, & graph editor to zoom horizontal
Similar to other 3D packages like Maya and C4D, navigating the viewport with zoom can be done by holding Alt and right click dragging horizontally or vertically. Dragging up and right = zoom in. Down and left = zoom out. Designer only has up and down.
Adding horizontal zooming makes moving between software less jarring, especially for new Designer users.
This would be much beneficial, as currently zooming behavior in Substance Designer (vertical only) is a total black sheep when compared with Maya, Houdini, ZBrush, and even with Substance Painter. Please, please.
