simplified basically everything to only focus on mouse wheel scrolling over the tabs anywhere from the page using modifier + mouse wheel

Version 2.1.0 adds TabWheel Search suggestions from recent searches, open tabs,
browser history, and bookmarks, plus /tab, /hist, and /book filters. Popup and
options controls were cleaned up with clearer descriptions, matching Refresh/
Reset buttons, and reset behavior that restores the current defaults. Private-
window searches are not saved as recent searches.

WHAT'S NEW IN 2.0.1

• Remappable click actions: Left, middle, and right click each now map independently to any of TabWheel Search, Browser Default new tab, Most Recent Tab, Close Tab, Duplicate Tab, Open Settings, or native click pass-through.
• Skip hidden tabs: collapsed tab groups and hidden panes now stay out of wheel cycling on Chrome.
• Smoother content-script recovery: gestures now work in tabs that were already open at install, after extension updates, and after enable/disable toggles.
• Safer restricted-page probing: TabWheel skips pages where content scripts cannot run without stalling wheel or recent-tab gestures.
• Smoother discarded-tab wake: cycling into a sleeping tab no longer freezes; the remembered scroll position is restored instead of being overwritten.
• Tunable page-scroll speed and viewport step cap, on top of the existing tab sensitivity and cooldown sliders.
• Hardened background stability: serialized writes and per-window gesture actions stop service-worker races from dropping updates.
• Reorganized options page with a reset-to-defaults button.
