1-Sorry, this is a current limitation of the code in the skin editor..
2-I do not know if this is possible.. I believe it is..
3-As far as I can tell there's no bug in the +1 function when used with search results (tested both on winamp library and file searches)..
PS: The skin editor was made by "lbooker" I merely fixed one or two minor issues with it.. so I don't know much of what's in there.
