Also curious what you like / dislike, and if there's a feature(s) you wish existed but didn't
Lastly, if you'd care to share, do you use it only for work or personal too?
Edit: typo
On a side peoject at the office, I mostly keep it out of Jira, and use Obsidan. I have a section for it in my daily todo list, that I use like a digital bullet journal. Then I have a file for various notes and reference information I want/need.
My other work stuff is in Jira. A team of 15, but really only about 2-4 of those I’m working with. Jira is mostly for show, no one is really looking at it and our user stories typically only have a title, if they exist at all. This is due to reasons beyond my control, as I’m no longer willing to do my scrum master’s job for him.
