Yes, sure. I don't think of program being unable to do something as an improvement, whatever philosophy might it be and I haven't experienced any glitches with scrot. More than that, I do experience it with maim (slop, to be more precise).

I'm not sure what could/should I report, but slop is terribly slow. That is, I'm moving cursor and the rectangle moves after it with delay of several seconds, literally. scrot -s responds instantly.

One more minor issue is that by default slop selects currently hovered window showing the border, but if I just press Enter rectangle returned would be still 0,0,0,0 which is kinda non-intuitive.
