How about moving this to 2.9 altogether? I will update the mod as soon as possible and we'll be able to work on 2.9 from then on, instead of keeping to 2.5b.
Right now I'm working on armor preview icons, I should add at least that and fire extinguishers to the new release as well, and maybe a few little things (sounds maybe poor compared to my usual output but I have much less time for modding lately. MONEY problems). Still no bigob for fire extinguisher but maybe I'll find something.
