Nice demonstration Gary. I've not used any 365 features yet. I've always felt a quick select tool would be useful to paint in and out region selections on bitmaps, like many pixel editors have, to make a mask shape. Particularly if it's a more complex (large perimeter) but contiguous shape. Some clips (e.g. first half of this one) of it being used on an (appropriate) image show a selection can be made in a few seconds. Maybe the region painter or something will have this capability in the future.
