Currently when you hold down shift to snap the playhead in the timeline, it snaps to the last frame of the layer (see image)
On most occasions when I do this, I want the playhead to be at the very end of the layer, not on the last frame. For instance, if you snapped to the last frame, then used the [ key to align another layer to the playhead, you'd end up with a one-frame overlap. It's a small thing, but a minor annoyance that adds up to many extra button presses when using the software.
I would like a preferences menu option to enable snapping to the very end of the layer, not the last frame.
