A client of mine wanted the ability to turn off and on galleries for public viewing... so I fixed it so it would do it by adding the word "temp" anywhere to the name of the gallery it only displays that gallery in the admin view:
I added the following code to: plog-content/themes/nameofyourtheme/collection.php
The below example uses the default theme that comes with plogger.. the two lines added are the first and last.
