[wanhuz]

Instead of AppList.txt only send games to the left screen, it should be able to execute different commands. This will solves games that has bugs like #22 , #19 , #5

Here's example of AppList.txt:

ChaosHeadNoAH.exe, "Sleep 5000, Send {f}" Firis.exe, borderless GenshinImpact.exe, manualdetect PhantasyStarOnline.exe, manualdetect Muv-Luv_Alternative16.exe, sendleft muvluv16.exe, sendleft Muv-Luv_PM.exe, sendleft
