I just wanted to say that I love this extension, it's changed the way I manage my googling/research/exploration in a way that bookmarks just can't satisfy.
I can't go back, and I may have become too reliant on it. I would totally pay for it once it's out of beta, especially with automated backup / cloud sync, and maybe some other integration with word processors or note taking apps, would be ideal for references and citations.
(I've had to make sure I keep the amount of tabs under 1600 though, otherwise it won't save new windows or export to the clipboard).
Anyway great work, love it.
