The underlaying mechanism works.
We have to have a closer look at the directories, that I did mark with TODO on a per tiddler basis. If the filter is used as it is atm, it won’t work too well.
Not every tiddler in every subdirectory has a tag at the moment. … So the OriginalTiddlerPaths tiddler is used to save them back, where they came from. BUT … It won’t work for new tiddlers, that’s why we need the $:/config/FileSystemPaths
Once we have rules for every existing docs tiddler in the system, we will have a deterministic way to know where new tiddlers will be saved to, depending on their tags or any other field, we may define.
This will enable us to improve the mechanism described in: Making changes to tiddlywiki.com via GitHub and Pull Requests (PR)
