Tag or categorize notes

[claudereal]

Currently, it is possible to create folders, but the solution is limited, we can't create subfolders or tags or categorize the notes.

It would be interesting to be able to tag with color coded the various notes in addition to the current folders. Also, have the ability to filter by tags. The goal is to be able to better find notes inside a folder because they may have the same main subject which is the main folder, but sometimes the notes also refers to one or multiple sub-subject.

I tried creating multiple main folder of the same main subject with additional details to cover the sub-subjects but it is not doable, because that's forcing me to duplicate the note in various folders. This is not workable because it requires me to update the notes in each folders. This is why I'm proposing this new feature. For now, for the notes that are in to many topics I'm forced to not use the Notes app and to create a doc file and put it in a shared folder with tags.
