I've read through the webstore link and the github page, and I'm clearly missing something. I don't see an option to save to folder via fuzzy search. In fact, I don't see options at all. I see a list of my bookmark folders with a search at the top. If I actually click on any of my bookmark folders then it just closes the menu.

It doesn't let me navigate through my folders, and it never opens anything.

Edit: Redundant

Hello, Better Bookmark author here. This extension is not meant to open anything - it's only purpose is simplifying the process of adding new bookmarks. It basically displays a list of your bookmark folders (flattened), and lets you select which folder the bookmark should go to. If you click on a folder (or navigate using arrows and confirm with enter), it should close the menu, but the page should be bookmarked into this folder. If it doesn't do it, it's a bug :)
