Uh, sorry to hear about the migration - it's understandable given the (over-)simplicity of Trello, but Jira seems like a jump to another end of the spectrum. We migrated away from Jira (Cloud) to Quire which has been amazing. The poor UX and performance were just making it a choire to keep the boards updated...There was famously a reply in a thread (on their forum) about performance issues in which team member replied that they don't understand what the complaints are about as most of their response times are "3 seconds or less" :)
