I like the extension FreshStart - Cross Browser Session Manager (https://chrome.google.com/webstore/detail/freshstart-cross-browser/nmidkjogcjnnlfimjcedenagjfacpobb)
It is a browser session manager which save all open tabs (or selected) to a new session. Sessions are saved in the "FreshStart Sessions" folder in bookmarks, allowing you to synchronize it with other computers. When I save session I can click on the icon and open saved tabs again in a new window.
I am looking for a similar extension (or other way) to have possibility to save session (i will like if saving is like the "FreshStart Sessions" - folder in bookmarks), but with pinned tabs. So when i save session with pinned tabs and open the new session (saved one early), this extension (or other way) to have possibility to keep pinned tabs as they were before - pinned.
