Volume badge on the toolbar icon
The extension icon now displays the current volume percentage in the corner whenever it's set above or below 100%, so you can see a tab's volume at a glance without opening the popup.

Remember volume per site
A new toggle lets you save a custom volume for specific websites. Set YouTube to 200% once, and it stays at 200% every time you visit — even in new tabs or after restarting your browser — until you reset it.

Version 1.1.0
New

Added "Reset All" button alongside the existing "Reset" — one click returns every open tab to 100% volume.
Maximum volume increased from 500% to 600%.

Changed

Per-tab volume mode now keeps each tab fully independent. New tabs and other tabs default to 100% instead of inheriting the last value used elsewhere.
Status labels rebalanced for the new range ("High Boost" now covers 200–400%, "Max Boost" covers 401–600%).
Slider center marker repositioned to reflect the new 0–600% range.

Fixed

Volume changes in per-tab mode no longer propagate to other tabs.
Boosted tabs are no longer reapplied to unrelated tabs after navigation when per-tab mode is active.
