* API.styles.* * API.usercss.* * API.sync.* * API.worker.* * API.updater.* * simplify db: resolve with result * remove API.download * simplify download() * remove noCode param as it wastes more time/memory on copying * styleManager: switch style<->data names to reflect their actual contents * inline method bodies to avoid indirection and enable better autocomplete/hint/jump support in IDE
