Right now the timeline Snap feature has no options - it works for all assets, and clips snap not to each other, but to TRANSITIONS, leaving gaps and unsynced layers, it's very annoying. Users have to manually check every clip for whether it snapped to other clip's border, or to it's transition border.
It would be great to have an option to disable Snap for transitions or for keyframes or for other types of assets, like we have in "Snap to" feature in Effect Controls panel.
