I tried out quite a few speed dial extensions to replace the one that comes by default. I didn't feel the others were properly set up in regards to simplicity and the right customization. This one tackles the things a user is looking for. You can add your own thumbnails, create folders, upload folder thumbnails, add your own background, add different tabs, and most importantly, you have an easy way to add or edit a bookmark. That last simple task is not always as straight forward in other speed dials I tried out. This extension gives you a lot of control.

The reason I am giving this 3 stars is because there are very obvious bugs which were not yet handled. For example, if you have more than two rows of bookmarks, you cannot always scroll down to see them. If you open the settings or theme editor, the bookmarks shift down. And there are plenty others I am catching like spacebar not working after a right click. This plugin has great promise and has a great way of organizing its usability, but to give a fair review, the bugs do need to be taken more seriously.
