Firstly i want to thank you for awesome pack

I have made a three icons for harmattan icon pack.

From the left:
im-gadugadu, MiniDLNAGui and CSSUfeatures


And two questions:
1. When submitting icons - do they have to be in 80x80?
2. 48x48\apps\leafpad.png Can you make this icon bigger and replace this one in 64x64\apps\ folder? Smaller one looks seriously better
