Data Crow went unmaintained just as I was starting to seriously look into it, and I ended up dropping the whole catalogue software idea. Good to see an actively maintained alternative that seems pretty feature rich too. And being KDE based is a nice bonus.

This looks nice, but without mobile support is a bit of a non-starter nowadays.

Tellico is a fantastic app. I used it for years, a decade ago, but at some point moved away when it wasn't fitting my use case any more. I guess in today's economy it's a bit old school, people are more likely using something like Obsidian or Notion. Good that it's still around, evolving even further.
