Agreed. What's the missing feature? Screen sharing? Remote sessions? Overlapping displays (doesn't work in Android BTW)? We've had all of these for years.
Even fractional scaling on hiDPI monitors has been good enough for me to not care for at least 5 years.
It's like systemd; the people bitching either want to sound contrarian or actually know enough to roll their own down to the low level. At which point I must say; show me the code. Open a PR or give it a rest
In Jira you have the concept of internal comments, which aren't visible to people outside the team.
They are useful for putting triage and debugging information in. Or even as a play by play with specifics so your team mates or manager can follow along with your progress.
Shortcut is pretty stripped down and lacks several features conducive to cross team collaboration. In particular I dislike shortcut's lack of internal comments. It's a much bigger annoyance than anticipated.
I dislike atlassian products in general, but having some discipline with the config/workflows was much better than shortcut.
