I always had problem with BigBox launching on a monitor based on screen index because the number (Screen 1, Screen 2, Screen 3...) can change if u turn on the monitors in different order, or use smart plug turns on monitors at the same time.
The workaround was to move the BigBox window with a hotkey via DisplayFusion, but now it's not even launching on the correct screen. It's set to Screen 1 at this time, but it keeps launching it on Screen 2 (bug #1). If I use the hotkey to move it, the Windows taskbar shows on top of BigBox. If I click on the BigBox icon on the taskbar, it moves back go Screen 1 (bug #2).
Besides from fixing these two new bugs, could you make it so LaunchBox/BigBox launches on a screen where mouse cursor is? A lot of games or programs already do this and I think it would be amazing.
