[Nathaniel Beaver <nathanielmbeaver@xxxxxxxxx>]

I've written a plugin to check that the target of a file link exists 
(see prototype attached).

However, I'd like to turn the broken links a different color by 
accessing the gtk.TextTag corresponding to the link and changing the 
style with something like

tag.set_property('foreground', 'red')

Unfortunately, I am having some difficulty finding the actual TextTags 
in the parse tree. Right now I am using tree.findall(zim.formats.LINK) 
to get all the links, but the node.tag property is just a string, not a 
TextTag.

Any suggestions?
