What
Several UI selectors were rewritten to read fields straight off a shared state object, covering loading state, submit count, last query completion time, the panel file view and the active REPL tab, and a command definition picked up the yields-to-panels flag next to a cancelled default. This is the panels and REPL-tab surface being connected to state.
