Better Feedback for adding to Groups/Frames

When dragging an object in the layer’s hierarchy to drop into an existing group/frame, that group could highlight someway that the selection is currently being added to this group/frame or another. Currently the top node is box selected, but this is not visible for large groups with many objects, it’s often off screen for me. I’ve seen a line down the entire left side of the group + contents to represent the current selection being this or that group. I often find myself dropping things in the wrong collection or else having trouble dropping between frames/groups, which would be the parent of both groups/frames, etc.
