Auto-rendering emoticons in a bug-tracker is dumb (because of course someone who pastes 50 lines of log output into a ticket wants to see smiley faces, blue stars, and thumbs-down icons, and SQL always looks better with broken hearts). Repeatedly closing support tickets asking for a way to turn it off is dumber. Forcing your customers to remember to manually comment out this misfeature in an XML file every time they upgrade Jira: priceless.

Sometimes you have to double-click to enter text in the form (interaction between Isso and Bootstrap?). Tab is more reliable.
