Here comes Papyrus - A marriage of selection store and Paper Folders.
Paper Folder - Files saved in <xydata>\Paper just like Paper Folders
Black Board :p - Files saved in <xydata>\Paper\Store just like Selection Store, but uses paper:<name> instead of tags. The file is saved on - 1. Showing the contents 2. Manually Saving it and 3. Launching other Paper folder
The Paper Folder contents are not saved in Permanent Variable, but the Black Board contents are saved in Permanent Variable. The PV takes preference over the file. So using Blackboard over Paper Folder is recommended when the collections involve Network locations (stale items required to be saved). Paper Folders recommended for Local files.
Note that, since only one Blackboard is in memory, you will have to load the Blackboard from the script after activating it to save the non-existent items otherwise they will be treated as Paper Folder.
Don't forget to upload your versions after making any changes.
