Thanks for sharing.
But I have some questions, after setting it up and using it… I don’t understand how this method can be different from a Folders and Files system.
In fact, each Dashboard is nothing more than a folder, but created manually. Right?
In the sample file shared by @TfTHacker (github) there is also a file that is never shown in any dashboard (/Research/What is Spaced Repetition and How to use it.md). In that case, how do you recover it over time?
