This is probably the main thing stopping me from actually switching to Studio One from other DAWs.
I know you can left-mouse drag on the timeline to move around when you drag left/right, but this is both annoying because the area is quite small (especially on a large screen, and you have to move all the way up to the top of the monitor), and also because dragging up/down zooms in/out, which is just incredibly annoying when you just want to move around.
