Seriously, why the hell is this approved ? We don't even know if Blizz Editor is going to have it's own highlight, and even if it has, it will most likely have different colors for the settings.
You don't even know Galaxy language complete API and the API is most likely to change as well.
Also, for notepad++ !? I would understand if it was for Linux because Galaxy will have more trouble running there then in Windows or MAC (their native distros).
Finally, and to conclude, GEdit is great!? What the hell is wrong with you!? DO you even know what you are talking about!?
I can't seriously think how this got approved. I simply refuse to rate something that is merely a WIP.
