I like your idea that the folder names are usually also the series names and, in this way, the series name is displayed above the "comics views". So I thought it would be quite consistent and practical that, in cases where a series folder has subfolders corresponding to several volumes, when we select one of these folders/volumes, the label above the "comics views" would show the complete hierarchy from the series folder. For example, I have a folder called Superman containing 3 folders named Volume 1, Volume 2, Volume 3. When selecting the Volume 2 folder, it would be cool to see the label above the "comics view" mode the name Superman - Volume 2 (or Superman/Volume 2).

Thanks for the suggestion, I want to add some more metadata support for folders to try to deal with this kind of stuff.
