Volume Manager is an open-source plugin designed for the Chrome browser. It allows users to control the volume of individual tabs, providing a convenient way to manage audio output while browsing the web.

With Volume Manager, users no longer have to struggle with multiple tabs playing audio simultaneously. The plugin enables you to adjust the volume of each tab separately, ensuring a seamless and personalized browsing experience. Whether you want to mute a noisy tab or increase the volume of a specific tab, Volume Manager gives you the control you need.

It's important to note that while using Volume Manager, there are a few limitations. Firstly, you cannot toggle fullscreen mode for the tab you are controlling the volume of, due to limitations in the Chrome API. Additionally, your system may not go into sleep, suspend, or turn off the monitor, as Chrome marks the current tab as "capturing" and inhibits these actions.

Overall, Volume Manager is a useful tool for Chrome users who want to have better control over their browsing experience by managing audio output on a tab-by-tab basis.
