Thanks for your detailed feedback :).

I just removed the annoying "Extension is blablabla" bar and concatenated the footer content for better space utilization and a 3x3 group should now be all visible without scrolling in 1920x1080 screens (zoom 100%). And more work will go into making the UI more compact in the future :). Any other weird stupid bars?

The other annoying bar in the top when you click `Alt` or `Ctrl` is so that you can type the number of the page/thumbnail and it can open in the same or new tab. There's also a hidden option that can make this only work when `Shift` is clicked, if you want to still use it to switch tabs and I use it personally (because I was just as annoyed as you and almost uninstalled the extension). It's the small checkbox in the top left of the newtab page.

I also think of doing something like 1Password extension in the future, where you use a shortcut and a popup would appear and you can enter the number of the page/thumbnail. And no I don't intend to add any adds to the extension :).

I just made some other changes too:
- Fix dragging and dropping images or links has to be exactly on the number or image (now it'll work on the whole thumbnail container/card).
- Add support for dragging links to thumbnails.
- Close the popup when a page/thumbnail is added (it previously just disabled the button).
- Fix default group is too small and has a funny name (name is now `Your Default Group` instead of `:)` and it's now 3x3 instead of 1x1).

And I really like my add-on too so you're in good company :). And please tell me more. I'm open to almost anything but never to a todo-list feature *_^ (I actually saw a speed dial add-on with todo-list feature).

2018-08-28: I also think of using the user top/most used sites in the default initial 3x3 group.
