How do you tab addicts manage too many tabs?

/Macapps helped me before and helped me find a great app switcher (Leader Key) https://www.reddit.com/r/macapps/comments/1pe04pv/need_cmd_tab_alternative/

I'm hoping you can do it again and help me find a tool or workflow for my tab addiction. I often end up with 70-100 tabs open which then slows down my machine and it becomes hard to go back and organize them.

I should probably organize them into projects by window, and then relevant tabs within that project.

Thing I think I'd want to be able to do include:

- giving a window a project name
- moving tabs quickly from one window the next to get organized
- close out a window but have it saved so i can bring it back up later

I tried workona and toby but they seemed slow and clunky (maybe im missing something). I'd love something fast and keyboard driven
