I have no problems with 0.7-3 so far, everything looks good!
Thanks for the 8x4 grid support!
I have only one feature request: Could you use the current theme background picture for application shortcuts instead of the custom widget one? It would look better (fit better to the theme).
Would be really nice!
These are the two files:
