So to avoid the hassle of organising folders, you create an editor with only a single folder that has 8 files in it? I can replicate this in a normal text editor by simply using only one folder with 8 files in it. For advanced CLI users, an even simpler (and arguably better) solution to this problem exists:

  vim notes/"$(date -Iminutes)".txt      # author a new note
  vim notes/"$(ls notes | tac | sed 8q)" # edit the 8 most recent notes, starting from newest
