Navigate boards, move issues, log time, and add comments without ever touching the mouse. Single binary, no runtime, sub-second everything.
No menus, no modals, no context switching. Just press a key.
Speed comes from architecture, not brute force.
All reads come from a local SQLite database. Every query resolves in under <100ms. No network round-trips for navigation, search, or issue detail.
Background sync runs every 60s, fetching only issues modified since the last sync. Initial sync pulls your full board; after that, it is incremental deltas only.
Comments, transitions, assignments, and time logs hit the Jira API immediately. No queuing, no eventual consistency. Your action lands in Jira the moment you press the key.
One command. No dependencies.
