For simple zoom in and move (eg offset to up / down / left / right) - size position rotate (SPR) filter is much easier to use than crop source, but crop source is much faster to export.
Id love to see this improved. Either by speeding up export of SPR by using crop in the background if no advanced features are present, or adding new crop filter with SPR-like controls. (Zoom do desired level + move to any direction with px offset and drag feature on screen)
Thank you for considering this
