JEDIT: Default forced subs suck. I tweaked them to look okay (200% size, depressed font edge, 0% background opacity), but they still alternate seemingly at random between the top and bottom of the screen, which is super annoying. And they are parly in, partly out of the letterboxing no matter what you do.
How did you manage to change them? I can’t even find a setting in the app to adjust… basically ANYTHING
