Cascading/hierarchical tags vs notebooks

[jkuns]

I like the light way of adding tags „everywhere I go“ over deciding upfront in which book I need to write a note.
Combined with an option of structuring tags by cascading them, it would be very convenient to organize projects, areas of interest, work…
A way to collect my ideas for a home renovation project could look like
#home / groundfloor / kitchen / storage
#home / groundfloor / livingroom / multimedia
#home / garage / tools / storage

This could also be used for a way to journal or put a date on your notes, if you cascade them like
#2026 / January / 15
#2026 / April / 02
#2026 / April / 15

in a one-level-tag-world all items in „storage“ (home project) or „15“ (date/journal) would end up in one collection

What do you think?
Would love to get your feedback on this idea.

Thanks for your great work so far !!
