While trying to replicate my GMS2 colour scheme in GMEdit, I noticed the following words, which all use the Constants colour in GMS2, instead seem to be lumped into the Keyword styling in GMEdit (.ace_keyword):
self other all noone global
Whether they should technically be categorised as keywords or not (probably should), it seems a little silly to not have complete parity with GMS2's theming ¯\_(ツ)_/¯
Edit: It also seems to me like extensions' functions use the script styling, instead of .ace_extfunction which I would've assumed is for extension functions?
