**This program is amazing. It's _easily_ my favorite extension of all time. In my opinion, it's _criminally_ underrated.** _Here's why I love this extension:_ As someone who regularly uses around 20-180 simultaneous tabs across 2-4 Chrome windows during a single browsing session, Tabs Outliner has let me do _so_ much more to keep track of and organize my browsing. There _is_ a learning curve, and sometimes the task of organizing archives of tabs can be quite daunting (I have >25,000 pages saved from over the years), but having the ability to store and rearrange them all is what makes it even possible in the first place, and that's exactly what Tabs Outliner does. In my opinion, there's absolutely no contest; Tabs Outliner DEMOLISHES rivals like LastTab, TooManyTabs, TheGreatSuspender, et cetera. Extensions like OneTab and Session Buddy show some promise and have small subjective appeal over parts of Tabs Outliner, but I still honestly think they don't even come close whatsoever. Unfortunately, the other extensions simply don't have _nearly_ the same level of functionality that Tabs Outliner does. I purchased the premium version a while ago, and it's been _completely_ worth it, even for a frugal soul like myself. It's a one-time payment to register your email/account as a premium user; I paid somewhere around $15. The functionalities, commands/shortcuts, and online backup services available to paid users are great. As awesome as I think Tabs Outliner is, I am still hoping for some improvements. The developer seems like a respectable guy, though the development process seems like it's been too slow for quite a while now. I think the extension still has a lot more potential, and I really want it to be realized. _Here are some things that could/should be added:_ Native bulk/multi-selection options would be great. Shift-clicking and Ctrl-clicking entries to move or delete them could be used to make the organization process _much_ smoother/faster. I would love to see a native filtering and searching function, and a sorting functionality. Preferably, these features would be applicable to large trees of windows and would run reasonably quickly. This would save me a huge amount of time when organizing my tab trees. I would also like a more customizable export feature that allows the user to set the format of the pages exported. Currently, I end up using a lot of text processing programs to help sort out my archives, but the process feels tedious and can be frustrating. Native sorting/searching, bulk selecting, or maybe custom exporting could help remedy this issue. Despite some things not (yet) included, Tabs Outliner is still very helpful and gets my full recommendation; the way I see it, Tabs Outliner is simply a must-have for Chrome power-users/browsing fanatics and is likely also very helpful for people who don't use chrome on nearly the same scale as someone like myself.
