It would be cool if the devs could implement a small window, a resizable, moveable, HUD element where we can type in plain text up to 255 characters (same as a single macro). Sometimes, I want to write myself a reminder as a sort of a to-do list for things in game. Other times I want to take notes about mechanics in a new fight without having to resize my window and open another application or even write things with pen and paper. This could also help other people for learning new fights if they could write things in the window like "if I get green mark goto A, if I get red mark goto B" etc. You might be saying "then people would just copy and paste an entire encounter's textguide into it!", but people can technically already do this anyway using a series of macros with the /echo command, so why not streamline it all together?
