2. When browsing handles for a specific shutter, items whose constraints the current shutter does not satisfy are filtered OUT of the picker and moved to the filtered-items list, which states the reason (e.g. the item's minimum shutter width vs the shutter's actual width).

3. Shutter-design items support equivalent min/max width and height constraints.
