It would be great (and minimize use of proprietary fonts) if applications 
(writer, others that include font selection options) used colors to 
differentiate between proprietary fonts and freely available fonts.  In 
addition to free fonts, I also have the ms fonts installed.  The way my 
feature request would work would be when I am using writer and have it open to 
a new document, the drop down box where I select which font to use would 
continue to show each font available to the application (writer in my 
example), but the background of each font selection would be a color dependent 
upon whether the font was proprietary (ms, etc), free (and unavailable to 
windows users) free (and available to windows users by default) free (and 
available to windows users by separate download).  

For example, ms (or other font provider) fonts believed to be restricted by 
patent or copyright, with a red background (in the drop down list), free fonts 
available to ms users with a blue or green background (in the drop down list), 
free fonts not available to ms users (or only available by separate download 
to ms windows users), yellow background (in the drop down list).  

This would enable two things, 1) a quick, visual way to select fonts for a 
document that the user knows she won't run into a problem with regarding 
copyright/patents and are available to everyone, and 2)would slowly increase 
the number of people/documents that use free fonts instead of proprietary 
fonts, and 3) would eventually put pressure on other proprietary font 
distributors/vendors to open their licenses otherwise face continued 
decreasing use of their specific fonts.
