Can it open a textfile, read its content, parse it, and perform actions based on that?
Can it also get information FROM the tracker instead of performing an action? For example, get the maximum length of the current song, know when the song is about to end, perform an action when the song ended and the tracker is no longer playing (can happen if looping is disabled), etc.
One could create a playlist engine this way which could be benefitial for one who wants to perform on stage.
Oh, and if possible, can the script generate a dialog with buttons and perform actions based on custom button presses?
For example, the script loads preprogrammed songs and waits for a button press to advance in the script.
