technical thought (skip this if you arent feeling technical).
seeing a need for a note that is somehow ephemeral. almost like a draft email. so it is saved, but the active version of can be updated, like subversion or other repo code management. This lends itself to information that should be stored, but also has a concept of past and present state, as well as an assumed future state that will be different.
maybe this exists already within the nostr ecosystem.
ideas this mimics? autosave functionality in ms office docs composed in o365, or saved to onedrive. unsaved persistent text files in notepad++. Wiki functionality in general, perhaps onenote in particular.
also just in general, would be nice to edit notes. not in a delayed save or typofix scenario, but days or weeks after publish.
