Fantastic extension, tried them all and this is the best for a modern looking speed dial that does a great job at grabbing the favicons.

The rest of it is just the icing on the cake, looks awesome.

Only thing I found that I thought might need some work is the page layout, running two columns I noticed that the height is being tied together, I have a hefty speed dial on the right taking up a lot of height, but I am only able to put one thing on the left of the speed dial that takes barely any height. Resulting in anything I add in the left column is going to be below the speed dial now, wasting so much space.

Edit: found a way around the above, but it's ugly and squashes stuff width wise.
