Like OneTab but leaner and FOSS. Named "Tab List Editor".
It started out with the idea of being a OneTab clone where I would release the source code but immediately I found stuff I could do better and lighter than OneTab. For example OneTab runs constantly, while this runs only when it's called or the tab groups page is displayed. (Event pages [this] vs. persistent background page [OneTab].)
Tabs are grouped by date. You can delete an entire groupe of tabs. When you click on "save all" a new group is created.
Options let you choose if you want to display urls and if you want to order tabs by urls.
You can also delete a single tab.
I advocate to keep only one group.
"Tab List Editor" capture only current window tab's.
