It's very easy to find yourself with a huge number of coplanar sketches
The most common use case I have for opening the Sketch (or any other) group is to turn off visibility for the last item, but when I open a group, it starts at the top and I'm forced to scroll through many irrelevant pages, hide, and then scroll back up to collapse the group.
It'd be great if instead when a large group is opened, it showed the first several objects [Sketch 1, 2, 3] then ellipses that can be hovered over to explode into the middle chunk when necessary, then the last few [Sketch 74, 75, 76] so the user could simply open the group, click the light bulb, and close it without having to scroll at all
