It appears I missed the rest of that thread, pictoratus. But I'll answer here.
The start menu shadow setting is in SKS6. It's on the Extra Settings tab for the start panel user pane. I never set fonts for classic widgets, as they tend to cause more problems than they're worth. I don't believe they are in SKS6, but if they are, I may not have noticed.
SkinStudio 6 is still evolving, so once in a while you may think of something that you can't find in there yet. In those cases I make adjustments manually via the Code tab for a given section, or I close SKS6 for a moment and edit the UIS file in notepad. Those situations are becoming more rare with each update to SkinStudio though.
CobraA1, SkinStudio 5 does not support the new features in WindowBlinds 6. I wouldn't recommend installing it if you're just getting into SkinStudio now. Do yourself a favor and learn it with SkinStudio 6. SkinStudio 5 becomes more obsolete with each update to WindowBlinds. There is also a good chance that if you edit a WindowBlinds 6 skin with SkinStudio 5 it will delete parts of the code that it does not recognize.
