Font Manager currently allows the user to:
* Preview installed fonts
* Easily activate and de-activate installed fonts
* Specify different directories to search for fonts
* Group fonts into "Collections", and easily activate or de-activate groups of fonts
* Export "Collections" to an archive for easy backup, sharing, etc.
* Provides quick access to the users font folder so that font installation or removal can be done by drag and drop
* It can also display basic information about the selected font, detailed information if gnome-font-viewer is available
In the future Font Manager intends to allow the user to:
* Export "Collections" to a PDF "fontbook"
* Compare fonts
