Neat! Looking forward to trying out the new changes.

By the way, you can use one account to post to all the communities. For you the links would be something like the following:

lemmy.world/c/opensource@lemmy.ml

So e guides here: fedecan.ca/en/guide/lemmy/…/detailed-overview

fedecan.ca/en/guide/…/how-to-open-in-my-instance

You could also keep using multiple accounts, but I find that to be more tedious.
