Offline support would be cool, but not useful enough to be a selling point for me.<p>My current employer uses Jira, and I find it to be decent. I&#x27;ve used Asana in the past, and I like it a lot, but it has its own holes and pain points. Same for Pivotal Tracker, Github issues, Redmine, Bugzilla... Every tool I&#x27;ve used has had some strong suits and some drawbacks—mainly related to how well it fits with the project and workflow. A big plus is if the tool has a good API (REST, plugin, etc.) so that I can easily write tooling to reduce friction.<p>Unless you can find a really strong selling point—and I don&#x27;t think offline support would qualify, for most people—I don&#x27;t see it getting much traction.
