I noticed on the wiki you can have mystic display random files simply by changing the last bit of the file name. So if I have a bunch of ans display files named say display, would I just put that to display and mystic will just select display.ans or display.an1 etc? Am I understanding that correctly?
Yes.
if you had display.ans and display.an1 Mystic would random select one.
