The original request was about avoiding to open the same file in two separate buffers and instead jump to the existing buffer when the user attempts to open an already-open file again.  Wishing to have multiple viewports open on the same file (and in the same nano) is an entirely different request.  It also has nothing to do with file locking -- that was just a suggestion to help the user to avoid opening the same file twice.  How file locking behaves is not the subject of this issue.  Closing this as too polluted.

My preferred outcome would be, if the file is already open elsewhere, to provide an option to open the file in view mode (like with the -v switch).

Combined with this, if there was a way for a file to be 'refreshed' during viewing mode (or even better, refreshed live rather than on demand), this would make it ideal for having a file open in two places for viewing, and editing elsewhere with changes reflected in the views.

PS. Currently 'refresh' only refreshes the screen. Not file contents. It is relatively trivial to write a macro that refreshes the file (i.e. a macro that opens in new tab, exits previous tab), but in view mode it is not possible to grab the name of the file (because writeout is disabled), so the filename will have to be hardcoded into the keystroke binding. Also, in theory there's no guarantee of 'refreshing' at the same line, though in practice, for some reason I don't understand, this seems to actually work if exiting and relaunching in view mode from the same terminal :)

The goal the user has in mind when they are using multibuffer mode and try to open a file is to view (and possibly edit) that file's contents. For that reason, a "nothing happens" outcome from the "File xx is being edited; open anyway?" prompt is the least useful outcome.

So with that in mind, IMHO that prompt and its behaviour should be:

"File xx is already being edited; open in a new buffer?"
Yes -> Open the file in a new buffer.
No -> Switch to the existing buffer for that file, if at all possible (i.e. when it's the current nano process that has locked the file).
Cancel -> Nothing happens.

Rather than the current:

"File xx is being edited; open anyway?"
Yes -> Open the file in a new buffer.
No -> Nothing happens.
Cancel -> Nothing happens.

With the new locking code, trying to open (into a new buffer) a file that nano already has opened, now results in the statusbar message "File being edited (...) continue?"  So you will not accidentally have the same file opened twice.

But I don't like the behaviour when answering No or Cancel: it opens an empty buffer, instead of renouncing the whole opening action entirely.

When using multiple buffers, nano creates a new buffer for each file that I open, even if that file is already open in an existing buffer.

This does not seem like a bug, but more of a usability issue. Many text editors check to see if a file is already "opened" in an existing buffer, if so instead of opening the requested file in a new buffer, switch to the existing one.
