Your concerns apply equally to notebooks and tags
Notebooks/Tags are good and bad at the same time, if you look for efficiency / productivity When you use notebooks/tags it is difficult to minimize the amount for notebooks/tags. You need to choose your notebooks/tags wisely else you end up with 100+ Notebooks/tags.And than the struggle begins:- You create a new note.. which notebook/tag to use? Did I already had one? Or is there a need for a new one.- The time spent in searching for the right notebook/tag (often multiple tags are used for 1 note), organizing the hierarchy, and maintaining correct spelling and removing unused notebooks/tags takes time (Lots of time over a month).
