I love being able to see product roadmaps laid out in both the Epic and Feature/Story view. This has been very helpful for us! Review collected by and hosted on G2.com.
If there are thumbnail images in JIRA, craft.io will NOT play nice with them. What happens is the JIRA ticket will update the craft.io ticket with broken image icons, which, if you then sync FROM craft.io TO JIRA, those broken images will then replace the thumbnails in the JIRA ticket.
