User writing a note like usual but before writing selects ‘Removable’ or whatever it’s called.
When they type, the app screenshots it instead of text on a note. The screenshot is sent to nostr.build, responds with the image, and posts that.
Looks exactly like text, but it can now be deleted.
Now integrate all of that into a single button to push above the keyboard.
Little problem we are having is IF someone already saw it, it will be stored in their cache for a while.
If you haven’t seen it yet, you never will.
