The best thing since sliced bread.

Really, though: this extension is a breath of fresh air when it comes to organizing your bookmarks. The UI takes a week or so to get the hang of, but after that you have to wonder why this isn't more common to have those game-changer buttons like "open everything and delete this group" in bookmark UIs. The "restore from delete" function means rectifying mistakes are ten second detours. Having your bookmarks in the form of an easy to pull up, easy to hide sidebar is great, and being able to choose a full sized tab when you need it is even better.

I've been using this extension for around a year without issue, and got the rest of my family on it the other month. All smooth sailing, and a big thank you to the dev for continuing to improve this critically useful extension.
