I haven’t had a chance to have a Tana account yet, but from what I’ve seen in Youtube videos, it seems like Metadata Menu could get closer to Tana’s user experience based on the « fileClass » capability.
Basically fileClass would be the equivalent of « superTags », but then I’d have to smoothen:
- the access to metadata from note’s links (maybe with a button that i could prepend to the note’s link?), to display them in a « note metadata modal » and give the user the capability to update part/all of them at lne time
- the capability to had a field to the fileClass from this note metadata modal
- the capibility to assign a fileClass to a note from the link (with another type of button) or create a new fileClass and creare fields for it….
- ….
I think all the logic is already available in Metadata Menu, and an improved UX is what I’ve had in mind since the beginning, but I would definitely need some ideas and guidance from UX design ninjas 
So don’t hesitate to throw ideas here or in the github repo’s discussion page Discussions · mdelobelle/metadatamenu · GitHub
