You mean combine the characters list with the _update list? I’ve developed my sketch to the point now where I can “pan” or scroll through a console larger than my window (think like a traditional ASCII roguelike), so I’m not sure that would work out unless I add an entire screen’s worth of indices to that update list whenever the screen is panned.
Otherwise, that would definitely be the way to go. I’m also considering having other layers (hence consoleRoot, as I may have other consoles).
