The extension is nice, it allows you to create a nice grid with pages that are visited and you can update their images. However the main problem I had with this extension is how a few things are not self explanatory or some defaults are not there. Basically, I should be able to select a tile under any situation, change where its pointing to, change the image and have it stay that way forever. Everytime I had to setup this extension I run into the same issue. If something manual was done to the tile it should be treated as law and never change that tile again. Maybe add a lock button when customizing a tile would be nice. Still I like this extension a lot and will continue using it.
