We really like the clean icon using the "SF" in #1. Is it possible to see a variation that has only an "S" in the icon?
Also, we'd like to see what it looks like w/ the icon to the left of the name as well as on the top so it can be used vertically and horizontally.
Finally, of all of the blue / green combinations, this one is the best, but feel free to try any other color combinations that you think would look nice.
