Seems you have translated good all my think
-blocked contacts : yep ok, I just listed it because I saw it in the StuffPlug options ; but it's always cool to joke with a friend
-Transfert limit : and no existing script ?
-5000 chars : ok ; btw I personally don't like the .txt file ; send chunked messages instead ? (part1, part2, part3)
-Actions/Invitations : same as blocked contacts
-group block : same(-joke +may be useful)
-content stealer : i'll take a look for scripts
-convo nick : what about it ?
Edit : "Anyways, Patchou doesn't like copying features from other add-on" : stuffplug will probably have no newer version, so .. (version for 8.5 was chance IMO)
