Continuity of folders with multiple sub-folders

There are some books that have multiple spin-offs / sequels, for those I like to create a main folder and then also add multiple sub-folders into that one, one for each series of the same franchise.

The problem with that is that once I selected a main folder and finished reading through all entries of the first sub-folder, YACReader will not display the next entry of the following sub-folder under "continue reading" - it will simply remove the current series from the currently reading list.

It would be nice if, after finishing all entries from the first sub-folder, the first entry from the next sub-folder within the same main folder would be displayed under "continue reading" next.

The main problem is knowing when a subfolder is a continuation or not. We would need some metadata for that.

Ah yes that's a fair point, I hadn't really considered that. For me, I only create subfolders for spinoffs of the same franchise but I suppose other folks might create them for stuff like genres and such too.
