This was an attempt at being able to show two messages at once. I couldn’t work out how to do it how I wanted and decided to give up.
It is usable in it’s current state, though. The current problems are:
– you cannot skip through the text while displaying the double message (You have to wait for it to type out).
– you have to add double message text with script calls which is painful and could be hard for beginners.
Still, it works and may actually be useful, so I thought I’d upload what I’ve got here.

Couldn’t you mix a word wrapping script to make it easier to call a double message?
Probably but I gave up on this one until I learn more :)
Hotfixed a bug that caused scrolling text messages not to work with this script by changing line 137 to
update_fiber unless $game_message.scroll_mode
Thanks for the script, hope you come back to this one!
