Just about everything. For Confluence, it's a complete mess. I can't find anything. When I log in, it shows me a page of irrelevant crap. It's something like "everything anyone in your group of hundreds of employees has written in the last 24 hours." So there's literally never been a single useful thing on the page after login. When I want to see the list of everything I've ever written, it only shows me the last month's worth. That important document that I need to update once a year? If I didn't "favorite" it, I have to use the search box and search the entire set of documents in my very large group. The text editing steals important keys for OS-wide functions. If you use Cmd-F to find something, instead of the browser's find feature coming up, Confluence steals it and puts up a much less useful find feature that doesn't actually find everything I need it to. I could go on for days about how awful Confluence is.

I don't use Jira as much, but as far as I can tell, everything that comes out of Jira is incomprehensible. I get lots of emails from its CI system, and they never have any useful information. It might indicate that a build failed or some warning was present, but it doesn't say what in the email, and there's no link I can click on to take me right to the logs. I mean there's a link, and it shows me something that looks like a log, but I can't find the actual parts where it built our product or what the errors or warnings were. It's basically just a web page of terminal output. No formatting to make it more readable, etc. Why not just send me the log if you're not even going to format it? It's so bizarre.
