Close all the tabs you no longer need in just one keypress.
Star important tabs, and close all the tabs you no longer need with just a keypress, like a boss.
Press Ctrl+Shift+S to star or unstar a tab. When pressing Ctrl+Shift+X, all unstarred tabs will be closed. For Mac users, use Command instead Ctrl.
Why is this useful? Because you can keep the important tabs on, like Google Calendar and Gmail. During some research, you may open up more than 20 tabs and only find 2 of them to be helpful. Star them, and cleanup all the mess like a boss. Remember to unstar a tab when you're done with it!
1.0: Basic star/unstar functionality, Ctrl+Shift+X to close unstarred tabs
1.1: Added Ctrl+Shift+S as the keyboard shortcut for toggle star for current tab.
1.2: Save starred tab on window closing and those websites will stay starred next time you open them.
Planned future features:
1. A list of favorite urls that are always starred until you remove them from the list. (e.g. your Gmail and Google Calendar page)
2. Customizable keyboard shortcuts in case of shortcut conflicts.
