Basically, I'm creating a launcher something like quicklaunch that allows you 
to use text instead of icons.  Since the text is the main focus of the 
plasmoid, I wanted to give the user the ability to customize it a bit.  Using 
the built in style works OK, but depending on screen size/font size/plasma 
theme it might be nice to adjust this (cf. the digital clock plasmoid).

Is there a better way to make these kinds of small adjustments apart from 
style sheets?

I don't really need to adjust the hover style and whatnot, but if I have to 
recreate the whole stylesheet to adjust anything, I wasn't sure how to go 
about recreating those sorts of things.  If there's a better way to accomplish 
all of this without style sheets then it's moot.

Thanks .
