Remember Auto-select setting ("Group"/"Layer") per-each-artboard. This will allow UI designers, Illustrators and Artists to have complex reusable layer structures as groups on one artboard and then just CTRL+Click (Autoselect mode) to select a whole group (structure) and drag-duplicate it to main composition artboard. If This artboard will have different Auto-select setting - "Layer" - it will be instantly possible to edit this structure so it fits.
Layers panel Auto-select lock flag for Groups\Clipping-Groups.
This will allow to lock contents of any group to be selected by Auto-select. Instead the parent group will be selected.
