On my website I have added the option of recursing into subfolders in basic mode (all my galleries are organized in subfolders to a gallry folder), and the link is then used to point to my galleries category view.
I have sent the improved version to the authors. Hopefully they accept this improvement and make it official.
Only a minor issue on 2.5.1 when open_basedir is in effect on the webserver - then it will not open. Bug found, and a fix is reported to the developer
Look for issue #40 at developers website - there is the solution (very easy to correct, should you encounter the issue)
