I was a big fan of pidgin, but this premise makes me feel iffy.
Why would I ever want my work to intrude on my personal messaging? My private time is my own. Slack/Teams is perfect because I can mute it on a schedule when I stop for the day.
Anything that is urgent can be managed via Pagerduty or similar on a controlled fashion
I loved Pigdin! The UI and brand was so good, too, for Linux back in the day...
The unfortunate problem with Pidgin is you don't have proper cross-platform E2EE chats, especially for groups. OTR is terribly outdated with its 1536-bit FFDH. These days the security margin sits at 2048-bit minimum, 3072-bit recommended. OMEMO might work but it's just not a standard. Good thing Signal made the whole thing just work.
