Add permanent boundary marker option for crop area for PIP window

[DavidRainey]

Per the Discord chat:

When streaming a cropped portion of a Display to another display, enable a persistent Boundary Marker so the user knows exactly what is visible on the Target and what isn't. My use case is streaming to a Virtual Display, then having MS Teams use that as the Shared Screen.

Is is possible to set up and store a persistent cropping? I will always want to have the exact same area cropped for my use case.

Many thanks for your support.

Sure, I can add a feature to always show the boundary marker.

Cropping should be permanent already. Do you have to set up cropping every time? Which app version are you using?

Thanks!
Re the persistence of the cropping - my mistake, it looked like it wasn't because I was fiddling with various monitors and resolutions.

The boundary would be very nice.
I definitely need this too. I use it for sharing 16/9 from my widescreen monitor. Thanks for the great app.
