Wow! This is an extension I never knew I needed! I have more than 300 tabs open at any given time, mostly for reffering to some content later on, and this is a nightmare for memory and processing resources. OneTab neatly put these all in one tab and I can restore and refer to them as needed, then add them back to OneTab when done. Bravo!

Suggestion: It would be great if there some sort of grouping I could do within the clickable list of tabs that OneTab creates. That would really help my productivity increase.
