Features
- Tabs: auto-hide the bookmark bar — show it only while the mouse is over the omnibox row or the bar itself, with a configurable hide delay. Turning the feature off restores the bar.
- Tabs: open dropped links in a background tab — dropping a link on the page content opens it next to the current tab and leaves the current page focused, instead of navigating in place.
- Web: confirm settings saves with a toast — every toggle, input and dropdown now reports success or failure. Also fixes
@blur/@changehandlers passing the DOM event asforceRecheck, which silently reset the update state and re-checked on every blur.
Bug Fixes
- keep the config page tab bar pinned while the page scrolls, so the active section stays reachable.
- hide the "excluded tab names" and delay inputs unless their owning switch is on.
