I would like to work on this ofc. ;-)

At the moment, I don't think this feature is necessary.
However, I'll leave it open if the necessity arises.

I was trying out an implementation for this, but it became annoying very quickly, especially in the status / help messages... 😭

I don't think this is necessary, since there isn't any other bot with this prefix. Anyway, it's a good idea to implementate it. PRs welcome, and Lucas could do something too

I would do this with a JSON db, just like this:
{"serverId": "prefix" | "default prefix"}

That's what I was doing, and that part is fine. It's mostly the status message that was giving me a headache, because that one is not server specific. It's specific to the bot user in general.
