Gmail Label Hider: v0.03
Ben Hengst
ben.hengst+glh@gmail.com

This script will hide any label that you rename to begin with 'x_' 
so for instance if you have a label of 'TEST' and rename it to 
'x_TEST' then you will not see it in the label bar on the side of 
the Gmail interface. 

KNOWN ISSUES:
Currently your labels can not contain certain characters:
{}
[]
()
(space)
.
