On a 4k monitor you can still only get about 80 characters of monospaced font per line, because of the "negative space" fetish UX designers have.
Something dead simple like posting a stack trace, and then having someone able to, you know, read it... It's just not something teams really does well.
I can understand how the tooling probably does a ton of stuff that corporate users want (integrating with calendars, tons of access controls for spaces for important people to talk, etc) but for a dev working primarily with a handful of other devs and qas, there is a feature set mismatch. I can't begin to tell you how badly I don't give a shit about 99% of its features.
It's been about 36 hours?
Maybe we're using an old version or something, but code blocks still don't expand horizontally to fill the available space, so we just get a horizontal slider bar.
Yes, that's my beef. If I need to juggle content to external text editors to read them, then IMO it has failed the categorical imperative of the tool.
