ah, cool. so, themes? the thing that almost every software out there makes as a lightweight pluggable?

not lemmy, no. in lemmy you recompile your app to get 'em. (source)

(edit: there's a special kind of thinking that goes into writing code this manner. this is pluggable (see extra_themes_dir) but consider the thinking that goes into writing code like this. "some bits static", with a maintenance burden and a recompile overhead. it's just absolutely fucking dumb)
