When I'm sharing my screen with krfb, I sometimes want to pause screen sharing to do something private that I'd rather not show the client (looking at a personal e-mail, for example). Krfb offers the possibility of disconnecting the client completely, but I'd simply like to pause the screen sharing, for example by showing the client a blank screen, or a screen with a krfb logo, and then resume the screen sharing. Would it be possible to implement this feature? Thanks a lot!
