Is there a chance that Cata will support grammatical cases? Some time? It would be a biiiig facilitation for translators.
If you mean things like word conjugation based on various factors (word gender, adjacent words, politeness or formality level, etc) it’s unlikely, gettext doesn’t support that kind of thing, so anything we tried to do would be some ad-hoc solution that probably wouldn’t work all that well since we aren’t linguists.
