Grouping Art-boards (Enclose with Rectangle)
When I build complicated APPs, I try to group them so be more clear what is where.
But when I draw rectangle it is impossible to enclose ArtBoards with Rectangle.

Thankyou for reporting.
As far my knowledge, Artboard is a master parent , you can do multi-selection but you can't group them or enclose with rectangle. Try to Zoom out or check in layers panel.
This is not supported but you can raise for feature request.
If you have further issues, feel free to report.
