Sounds good. If this was implemented I’d like the ability to remind myself about other people’s observations too. For if I’m identifying and see something which I think I can identify if I get out book but don’t have time or don’t have the book with me I could flag it to come back to later. I’ve occasionally used star for this.
I could use an another reminder app like https://www.rememberthemilk.com/ (other apps area available) but something built in would be easier and make it easier to remember to add the reminder.
