My biggest complaint is the nonsensical UI. I never know when I click a ticket if I'm going to get a) a split screen view, b) a modal pop up, c) a full screen view, or d) sirens in the distance.

When I click the 'back' button, I never know if I'm a) closing the ticket I have in a split screen, b) going back to the search results, or c) going back to Confluence and losing my search results and wondering how I was in Confluence to begin with.
