What a great suprise. Today just installed fedora on my laptop and will be giving new client a spin. The only thing that lacks in Gnome is that dino can't stay active in the background. Since years it's a requested feature. There are some workaround but they usually don't works.
I wish the Windows XMPP client situation was a bit better, but in the Linux world we have at least 2 actively maintained and modern-looking clients with Dino and Gajim, and 2 TUI ones.
