Indeed, I suffered from the same lack of knowledge. Been a long-time Mac user and entered the world of Affinity by the discounts during the pandemic. Thank you for that. However, never figured out how to rotate a selection frame without the actual pixels. Modifying the selection is so standard in Photoshop and Photoshop has such a huge influence in muscle memory that I never thought about masking. For all others coming to this thread after desperate searching, here is the workflow I figured out: Press [M] for drawing a selection e.g. rectangle as a good starting point Press [Q] to switch into QuickMask mode. Press [V] to use the move tool and modify the area as required: Resize, rotate and position as needed. Press [Q] again to leave QuickMask mode. Now you can apply filters or use the selected pixels in the intended way (move away, delete, whatever). (Sometimes the selection is gone after leaving the QuickMask mode. Does never happen whenever the area was moved during masking. Have to use this technique more often before I submit an actual bug report; maybe someone noticed this glitch as well or is it a common failure for newbies? ;-)
