is there a way to always, right above the current, display a line in light grey with the contents:

01234567890123456789012345678901234567890123456789012345678901234567890123456789

did the key of melpa just change again? from 61:c7:72:3a:... to 22:77:d0:87: .... ? this seems like it's the third time it's changed this year, which is weird

@qqq I believe emacs has something called overlays that can be separate from the buffer itself

not sure about the specifics
