the_ult: I believe it's already in the works. The settings for the plugin has a "each film has it's own folder" setting. At least to me that would translate to that function.
Yeah, normally if a folder only has one file in it or a two or three that have been grouped together it will use the folder name, otherwise the file name. Some of it is configurable, read armandp's post above.
that's entirely correct.. it's even had a makover in the current trunk (for 0.5.3)... note that the Use Folder Name setting differs from 0.5.2 (default setting is True in 0.5.3)... but it's smart in using Folder or File names like fforde mentions. If the folder is "cleared" to be used for the name it will use the folder name.. if you set it to False it will use the filename.
