ACK!
I will now be able to increase my number open tabs x100 :D
Another similar extension is Session Buddy, which comparable features and additional ones, easier for managing your sessions, moving tabs between open windows, saving them, and have an overview of all open windows and all the tabs.
Also, it automatically saves a snapshot of all your open windows/tabs, useful for when Chrome crashes and cannot restore its windows.
You can also save different sessions, and have your own snapshots in time.

A big differentiator between the two extensions is the permissions they need :
– OneTab : "Read and change all your data on the websites you visit"
– Session Buddy : "Read your Browsing History" and "Display Notifications"
I tend to find the latter less intrusive
