This is something I should have reported from previous versions.
When your program initiates pop-up notifications, they often do not appear over the main application window. The problem with multiple monitors is that they can pop up where not expected.
Is it possible to have all pop-ups appear over the main application window? It would be simple enough for the user to close them or move them out of the way. In this way, they can be easily found without searching on additional monitors.
As always, thank you for your efforts on this great program.
