Export

The export feature allows you to save your lists of open or saved tabs into a HTML file. This HTML file can then be used to import the tabs back into the extension on any machine, either adding them to your saved list or opening them directly. This makes it easy to back up, share, or transfer your tab sessions.

Options

Full-screen dashboard	Popup → ↗	Expands the popup into its own tab for large sessions.
Export/Import/Share	Popup bottom right	Creates a page, that can be shared with others; import merges with your existing open/ saved tabs.
