Why don't you give some idea what you're looking for because I really have no idea. Doing a rotation should be a bannable offense so I assume that isn't what you mean which, to me, leaves little more than key assignments. Most of that can be done with just the key bindings in the game since there isn't that many keys. There's 12 main panels, i.e. inventory and such, and 12 function keys, hum. Beyond that there's just emotes. I did a lame dance using the point emotes. Mostly it doesn't seem that useful without addons. Many of those add key bindings and slash commands that let you turn UI elements on and off. I suppose one could toggle the main interface elements on and off. So what, exactly, where you thinking?

Things like player stats (as Crassius said), showing things like bag space, fps, zone name, level, experience, gold, soul gems, ... are more examples of things that could very nicely be shown on the various enhanced-keyboard screens.

@LilBudyWizerub17_ESO sorry taken me while to reply to this thread, been busy, as @Crassius stated im not looking to bot, I would love in depth stats to be available on the go without having to stop and open my screen, softcaps, gear damage and buff/debuff stats would be awesome on the lcd, but like @Stv has said it doesn't look likely if the api can't access it, to be honest its hard to find any real good apps for the G19, at least not for the games I play lol
