For example, the auto-merge functionality is somewhat useful, but it sometimes gets it wrong. Both merging and splitting alerts is extremely clunky. I'd also love to be able to have policies like "this alert is low-priority outside of business hours". The ability to re-open an accidentally closed alert. The ability to edit the alerting rules (the Global Ruleset) without needing to be a super-admin, as the Power That Be are reluctant to hand that out, also, the ability to just read the Global Ruleset with my peon privileges.

… the sort of spit & polish that doesn't happen, IMO, anymore, because everything is an MVP feature, before the agile scrum PM moves on to the next MVP feature. "Polish" just accumulates in the JIRA graveyard.
