Group your tabs into groups.
Had lots of tabs open which I wanted to group and organise... Created and named a new group in the extension, dragged and dropped a few tabs into this, one by one (it doesn't select multiple tabs). Then clicked on "work with this group" (there isn't much else to click on)... The extension closed all of my other tabs in one swoop, and bypassing the Chrome history at the same time, so no way to restore them! I feel rather stupid that this happened... yet I am posting about it, so you will not make the same mistake. AVOID THIS EXTENSION (sorry for having to say so)
WOULD NOT RECONMEND BETTER YET STAY AWAY FROM THIS TYPE OF EXTENSION, it opened my tabs in seperate windows which kinda looked like malware but i had this type of thing happen to another extension i used which i would also advice to stay away from (workona), not only this extention did that it also removed my tabs and would not let me restore tabs. it also doesnt really organise the tabs.
