 - First-run setup remembers each backend that finished it, so switching back does not repeat setup, and the launcher gates playback on the backend the running app started with. Current incomplete or cancelled setup takes precedence over stale completion history.
 - Stats dashboard mining and deck lookup use the selected backend. Settings labels for popup pause and the dictionary deck no longer name Yomitan, and the backend selector sits with the other dictionary settings.
 - Hachidori scans, dictionary counts, and settings reads wait for the dictionary engine to finish loading or importing instead of caching empty results.
-- First-run setup can link an external Hachidori dictionary host in an app, browser, or Docker container, verify its library, and unlink back to local dictionaries. The optional host controls are collapsed by default and explain which apps or containers must stay running. Unresponsive connection checks time out so setup remains usable. Anki mining and media enrichment stay in SubMiner.
+- First-run setup can link an external Hachidori dictionary host in an app, browser, or Docker container, verify its library, and unlink back to local dictionaries. The optional host controls are collapsed by default and explain which apps or containers must stay running. Unresponsive connection checks time out so setup remains usable. Anki mining, media enrichment, and custom toolbar buttons stay in SubMiner, including when editing buttons while linked.
 - Hachidori frequency highlighting reuses dictionary-entry ranks and fills missing ranks through its existing API. Entries without a matching definition may remain unranked. The bundled integration is maintained in a pinned fork submodule using upstream HoshiDicts and WASM binaries.
