Would it be possible to colourise the Output text so that when a show_debug_message("Hello world!") message posts to output that it has a different colour to the other general Output text?
(that’s a Builder question rather than GMEdit question then?)
Builder intercepts output from GameMaker runner and GameMaker does not automatically tag messages at all, but you could modify this bit to use a FileKind with a syntax highlighter assigned so that you could then recolor lines based on prefix (e.g. color lines starting with ‘[error]’ red).
See ini-editor for an example of defining a custom Ace mode.
