I love the range of customisation options but when I close my browser and open it again, it resets to the default and all my saved preset is gone

I must say that I liked it a lot, I think it's great in general, except for one thing that makes it almost useless, and I hope they fix it or change it as soon as possible and that is: being a bookmarks extension the most obvious thing is that one can import all the bookmarks you have in Firefox or in another browser, that will accept to import them in a JSON or html file, but it turns out that only allows to import the bookmarks from the same extension? so if you are a new user you are screwed, and then the developer of this extension expects you to import one by one Firefox bookmarks to night tab, which is not only ridiculous but a useless and titanic task! I'm not going to put one by one, if I have about 2000. Anyway, I hope they fix this soon, because the extension is great and looks promising, because if not it's a pity it's only for a few.

Decent and privacy respecting.

Search engine defaults to Google, and the "Cool stuff" section comes with links to GMail and Google Drive. There's settings to change that, but there are a lot of settings, and so it feels a bit daunting to configure when search and shortcuts work fine in the default FF new tab page.

This is the best designed dial that I've found, but it needs to sync with the bookmarks folder to be useful. I have way too many bookmarks to add them one by one. If this were implemented, then I would definitely rate it 5 stars.

The groups need drag and drop sorting as well.
