There is a symlink trick on the server side. It's a little annoying that it is only a workaround, but one set up it's great! I was looking for the git issue where i found it, but was only able to find this one (it seems to be documented now).
left is definetly not always off. i am curious what you mean by delayed effect that cannot also affect a checkbox. especially if some cookie settings now havetoggles with three options, each one in a different color, some just slide between the rightmosg and middle option etc.
no matter what you say, this is not intuitive, a checkbox is! if there are more than two options, choose another ui element. foem over function is way too common for (at least my) comfort nowadays
one thing still stopping me from using it is the lack of upload links. if i cannot send a link in my vacation group that everyone uploads their images to, the tool is out of the question.
i don't think that's the reason, there are just too many clients availabe and too many inconsistencies between them. aside from that i don't think there is a really good one for ios and no go to solution for all platforms in general.
but please correct me, if i'm wrong, i'd be really happy if there was an easierway into xmpp especially for non technical users. matrix does a better job at that even if there is the problem with metadata protection.
another reason to mention matrix, but not xmpp is the easier handling of he concept of an audio call room. for this reason i was also surprised ro see IRC mentioned here.
correction from my side: it is the development edition, which means rolling release and possibly less stability, but it is worth a try imho (but i do not use it personally)
you could have a look at etherpad. seems pretty cool and is extensible with plugins. i don't know about resource consumption and security aspects, tho, because i don't personally use it. there are also a few publicly usable instances to test it out (see their github). keep in mind, however, that those come with plugins and do not reflect the vanilla state of the tool.
