SPR filter snap to grid

One suggestion about the SPR filter:
The SPR filter only snap the center point to grid, can you make the border snap to grid or edge, too? The border has a shaded area and a white line, which is not easy to align to the edge.
Thanks…

It already does, but the locked aspect ratio in the default Fill size mode makes it less usable. If you switch to Fill or Distort you can clearly see it works.

Sorry I can’t see the difference. The clip edge won’t snap to video edge in fit/fill/distort mode.

It only snaps the handle you are dragging to an intersecting grid line. It does not snap edges to lines when you are dragging the center positioning handle. That handle too only snaps to intersecting lines.
