I agree. Though I have had good success with NIP-09 deletion requests, and although certain devs are trying to rally against it (FJ for one), and some other clients still don't allow them, I am grateful that #Amethyst supports edits. It should be a standard functionality, even if it were limited to something like three edits or for 48 hrs etc. 

 I have used Amethyst but like the interface and functionality of Primal so I have been using that but may have to go back and try Amethyst again. I get the reasoning of no delete but at the same time I wish I had total control over my own notes.
