Review for Extra Folder Columns by Richard Cotterell
Rated 2 out of 5 stars
What cannot be understood is why a patch is necessary when the author can make the changes for a clean add-on.
I'm having to come to the Windows section in order to see IF I can change the two lines in the "rdf" file inasmuch as in Linux changes CANNOT be made to the file due to a known issue with tar files.
