Hi, fantastic gallery. I've gone through 3-4 others and finally found one to stick with.
The directory tree is causing some unwanted behavior when it is unhidden and the window's width is already used up. Say you're looking at a list of galleries 7-wide. They take the entire width of the screen. If you then expand the directory tree, the gallery thumbnails are pushed to the right and instead of dropping the right-most thumbnail down a row, and left-right scroll bar is created.
Furthermore, when a branch of the tree is expanded the thumbs are *helpfully* centered which unhelpfully pushes the directory tree to the left of the screen.

thanks for the help!
