I just noticed a bug in version 2.102
If you have "Create folder.jpg file for each folder" enabled and you already have previously saved a folder.jpg file in a specific folder, when you use the Poster Browser to modify a poster, the changes isn't reflected in the "folder.jpg" file. It is not modified at all.
However, the .tbn file is updated.
Proposed fix : Modify the folder.jpg file at the same time as the .tbn file when saving a new poster.
Thank you for looking into this. I have different apps using both files and I would like to keep everything synchronized.
