Studio One has a lot of Snap to options like Snap to events, zero crossings, cursor, loop......but not to markers.
This feature could be particularly very useful while scoring to video. Here's a proposed workflow that would really benefit from having this feature :
You have imported the video on the video track and have set the marker track with timebase to seconds, where you will add markers to important things happening in the video (on a per frame basis). Now you open the tempo track and add tempo points on starting of the bar located nearest to those markers you set earlier to the video (typically during a spotting session). So you try to drag these tempo points (that you have set to a bar start) and try to make them snap them to the markers (which are synced to imp situations/frames in the video), so that you can have each idea/motif at the starting of a bar and so that your music perfectly aligns with the grid and tempo changes in the tempo track. But since there is no option in Studio One currently to enable snapping to markers, doing this entire task is a freaking nightmare.
It would be so useful if this feature is added into the future updates of S1.
