Has anyone tried this extension? Looks interesting...

Okay I used it for a few minutes and I think I really like it! The extension is called Toby. It hijacks your New Tab page into a page where you can drag and drop your tabs and organize them into "collections". When you move a tab to a collection, it removes it the tab bar at the top of chrome, and you'd find it instead by opening the New Tab page and looking in the relevant Collection.
There's something called "tags" also which I haven't tried.
From the new tab page, you can save your session, open a specific tab, or open a whole collection.
If you create a free account you can sync your saved tabs between devices which is really nice. There's a paid version also which is for teams but the free version is unlimited for a single user. (If you don't create an account, your saved tabs will be saved locally on your computer.)
A couple things that I don't like so far (seem to be bugs):
1. When you drag a tab to a collection, it doesn't immediately remove it from your list of unsorted tabs. However, closing the tab you're in and opening a new "new tab" page will make it update.
2. Another thing - if you click to open a tab after you did some organizing, sometimes it opens the wrong one. Seems like a bug.
Hopefully they'll fix those things at some point!
Anyways, just posting my experience so far in case it helps anyone.
