Feature request: all notes in a single file

[Nadano]

I believe that it would be useful to have the option of placing all the notes in a single file next to the original one named "original.linenotes" or something like that. In between the notes there could be comments with the current name of the file used and if users break the format, well, too bad for them... This would be particularly useful for teams that are not used to git, so they don't have to add multiple files at each revision. It would also help having an overview of the "open" notes that must still be addressed.
