SigmaOS

One window. Many workspaces. All your tabs

Overview

With SigmaOS you can build your own Browser. Your tabs are laid out vertically, like a to-do list. You can group tabs easily, rename them, lock them, snooze them for later or mark them as done.

SigmaOS could save you a lot of time and space, personally I have around 10-15 tabs open all the time so I think I'll give it a go.
