The three things that annoy me the most about the console:
1) state management/sync is frequently terrible. E.g you are looking at a page with some health indicator and a log view. The last entry in the log is some variation of "transitioned from busted to not busted", but the state indicator doesn't update until you refresh.
2) if you have multiple tabs open at a time (pretty common use case) there is a good chance it will suddenly decide that you have to reload the page for some reason, often when you are in the middle of something
3) live updating. Why the hell do I have to sit there hitting refresh on so many of the views to get up to date data? I've often sat there waiting for something to finish, only to realise it's been done for a while but the page has not updated. This seems closely related to (1).
I find the overall design of the console fine, generally the UI is manageable, but the actual implementation is a steaming pile.
