+1 for Cluster. I settled for OneTab like many, until it deleted all my tabs. Happened to many people, and is fatal. Then I used Session Buddy.

Cluster works great with a big screen too which is what I have. https://chrome.google.com/webstore/detail/cluster-window-tab-manage/aadahadfdmiibmdhfmpbeeebejmjnkef?hl=en https://chrome.google.com/webstore/detail/cluster-window-tab... https://chrome.google.com/webstore/detail/session-buddy/edacconmaakjimmfgnblocblbcdcpbko?hl=en https://chrome.google.com/webstore/detail/session-buddy/edac...
