So you click on a handle to begin your drag and you hold your click, you then move your mouse to what it is you want to snap to (it would need to be visible on your screen)
this would save me a lot of key command presses/clicks, as sometimes I am very back and forth between Event snapping and Grid snapping.
During your drag/resize, you could position the mouse over other events on other tracks, a ruler track, or the top most main locator timeline for grid snap and or locator snap.
I’m still pondering the protocol for this, but that would be best for people at Steinberg to deliberate. But I think potentially, this could work even if Global Snap is turned off. ie, this would be an “Always On” feature (but an option in preferences.
So essentially when this on, and you are click-hold dragging event size, once the mouse leaves the track/channel area of the event being dragged, then this smart mode engages.
This means, that even in Global Snap is on, and set to Grid, it will be ignored and or combined with Smart Snap when the mouse has been moved to be hovering over other tracks/channels with events to snap to, or ruler, or top locator ruler.
This is very handy because someone could have multiple ruler tracks with different time/grid displays, and just hover the mouse over them to snap to that particular ruler.
