Tabius

An automatic Tab Grouping extension for your browser. Tabius is a customizable and easy to use Tab Grouping assistant for Edge.

If you use tab grouping or couldn't use it due to lack of options, Tabius is a must have extension for you. The extension is packed with useful features like:

• Automatically create new tab groups when you open a link in a new tab.
• Limit the browser to only create groups if the new tab matches the original tab's domain.
• Create custom tab grouping rules: always create tab groups with a specific name and color from your favorite websites!
• Don't want to create tab groups from a specific site? Create a blacklist from the settings or add the site to the blacklist right from the toolbar!
• Option to close an existing tab group when there is only 1 tab left in it.
• Limit maximum number of tabs allowed in a group.
• Automatically name tab groups based on domain/subdomain or the full URL.
• View current tab groups and act upon them by clicking on the extension icon right from the toolbar.
• Sync all your settings and custom lists with Edge.
• ..and many more features.

I created this extension from my need. I use tab groups all the time and the extension helps enhance this feature.
