Saved settings and exports

Popup (via chrome.storage.local): the last generated command and port, recent-ports history, headless/%random% toggle states, OS selection, custom Chromium binary paths and arguments (per OS / per path), and whether you were connected (to auto-reconnect next time you open the popup).

Inspector panel: only your custom device profiles persist (also via chrome.storage.local, synced live across open panel windows). Everything else - scale mode, mouse/touch mode, split position, message filters, the max-messages limit, Network tab contents, and custom header drafts - lives only in memory for that tab and resets when you close or reload it.

Custom header drafts survive closing and reopening their dialog within the same inspector page. Clear headers explicitly discards both table and JSON drafts; they are not stored in chrome.storage.local.
