Hello from Spain.
Congratulations on this very intuitive software and especially on the great idea of making everything configurable.
There's a very useful feature that other programs have had for some time... It would be very interesting if, in video projections, the image could be moved and its dimensions changed by dragging the edges with the mouse, and also the geometry could be modified, since it's not always possible to position the projector perfectly centered on the screen, and some budget projectors don't have the Quick Corner function. This feature is also very useful when doing mapping.
Thank you
