The note-takers that I use, use folders.
I'm used to using folders.
How do you mimic folders in Google Keep?
One thing that I thought of is to keep a separate note that has the list of all tags, but it's too much work writing a tag and then putting it in a different note. Clicking in the list of folders is faster.
