I use all 3 for all sorts of things.  Stuff out in the open - what is perceivable and not hidden - !pcnote aka group. Like walking into a room and giving them a description.   Stuff hidden, or investigating objects will use !selfnote so the other players wont know what he/she may have found. Like opening a drawer and finding a gun inside the drawer.  sometimes, the hidden stuff may have an additional saves and I'd like to store notes in there, that the player won't see. example: "!selfnote: You found a gun in the drawer" (GMnotes: Have the player roll a perception check, if pass: etched on the side of the gun is the name of the owner)  -----------------  If the GMnotes is unable to be displayed for DM eyes only on !selfnote, is there another way to achieve a whisper to GM? an example I can think of is "It's a Trap" - Secret Notes. That sends a whisper to the GM.   !selfnote --template|name of template --gmnotes|notes here
