There could be a 3rd problem, when saving/restoring buffer-local mappings. Because, between the moment when you saved the mappings, and the moment when you try to restore them, the current buffer may have changed.

And then, Restore_mappings() would use this info to restore the buffer-local mappings in the right buffer. One could probably use the :bufdo command, prefix the latter with a count (matching the buffer number previously saved), and suffix it with the mapping command.

We would have to check first if the buffer still exists, using the bufexists() function, because it could have been deleted in the meantime.

In this case, maybe the Save_mappings() function could be improved by saving the number of the current buffer (bufnr('%')).

Maybe something like:

:{original buffer number}bufdo {mapping command}

With it, you could save the mappings using the keys C-a, C-b and C-c, in normal mode, inside a dictionary:
