I have been working to organize a little bit. The session planner is a nice overview of things, but it would be cool if you could make a note in the campaign codex into a subnote (Kind of indented a little bit). 

I would like to have Like a session note, slightly indented the question note I might use, or like an encounter note. Likewise on my primary campaign note, to have my character notes and locations subnotes.  

For example: 
Campaign of Three
       Characters
       Locations

Session
      Dragon Quest
      Dragon Lair - Exploration
      Dragon Lair - Map
      Cultist Encounter
     

Maybe even have the subnotes have categories that match the columns from the session planner. 

Just a thought.  Keep up the great work. 

Hey, thanks for the feedback. So I am not sure if you grabbed the latest update, but this past release has some features with codex that may be close to what you are asking for. To get it, just download the app and install it again.

Be sure to take a backup in settings before this version, just cause it was a lot of changes. The new features allow you to nest notes in both campaign codex and session planner. Here is an example; just let me know if you mean something else. Your data should be safe so you shouldn't need to restore the backup, but it's best to take one in case
