Jira is a Golf Course Sale
Everyone who uses it hates it.
People who buy it, don't have to use it.
Nasty, poorly designed, poorly implemented, slow, memory hog.
Jira is bad software made badly by bad people who drink bad coffee, dress badly, and are bad at their jobs, and should feel bad.
And their dogs are bad dogs.
Seriously, no full text search over all fields? WTF? That was old tech in 1975.
Stop trying to design software. You are no good at it.
