It would be great if there could be an option to disable the automatic detection of display changes in v3 so that OpenLP remembers a particular configuration of displays.
Otherwise, depending on what order you set things up in, OpenLP is continuously changing its display setup and you keep having to go in to the options to reset it.
For example if someone accidentally unplugs the projector, OpenLP reconfigures itself to show on your laptop screen, then when the projector is connected again, you have to go into the options to make it work. Or if the projector is unplugged at the end of the service before OpenLP is shut down, the next time you start OpenLP you have to reconfigure the display options again.
I may have missed something here but v2 didn't do that, it would remember the last setting even if the displays were not the same. This was easier for the tech team as it didn't matter what order things were plugged in / started up.
