Lemmy 1.0 will have community summaries as a separate field from the display name and the sidebar, so hopefully people will stop using the display names as summaries (cough!climate@slrpnk.net, !egg_irl@lemmy.blahaj.zone).
Yep, that's the most common solution (I do that, too). Though I also do some "smart" splicing to try to detect the description part and cut that out, but it can't cover all cases.
I've been doing that for ages now: splicing it at : and - and using the first array element. It's just annoying. That, and having to watch and account for false-positives (e.g. X: Files, Self-Hosted, etc). And some places it makes sense to show the full name, but it often still gets truncated in CSS depending on device width. Plus, some community display names don't use that format :(
Was trying a different approach this time around, and it clearly didn't work out lol.
