Feature requests: Zoom by middle mouse click + large quantize option

Hi, long time Cubase user and I thought since ages it would save lots of time to be able to zoom in/out by a simple middle click and dragging up and down. (Just like when dragging in the ruler). Left and right already now navigates the arrangement, then up and down would zoom in/out. Please enable options for mouse middle button functionality.

Another time saver would be if the maximum snap quantize was much bigger than 1 bar, like it is now. When you are all zoomed out it’s quite difficult to drop events on the intended place, say bar 136. You always have to zoom in again to make sure copied parts landed in the right place.
In other words, please make “adapt to zoom” truly adapt, by enabling much bigger quantize levels than 1/1

Thank you
