This is for the devs. It's ok when people complain. When your project catches on and reaches a certain level of use, you will be faced with an infinite stream of complainers. There's no way around it....
Calle: I love jumble the best! have not had anything to be serious about yet! Good luck! If' they do not like this noster, or fediverse instance etc. Tell them to find one that works for them the complainers then! *Thumbs*-up.
