Hi,

Looking in the definition of interleave-mode, it should be a buffer local minor mode. But if one wants to add hooks for interleave-mode, for example,

    (add-hook 'interleave-mode-hook (lambda () (print (buffer-file-name)))))

can see that when enabling interleave-mode, it prints the pdf buffer file name, while prints the org buffer file name when disabling. That's a bit strange as we enable the mode in an org buffer while disable it by interleave-quit in a pdf buffer. Anyway, shouldn't these two be the same(as the mode is buffer local)? If not, there may be issues when people trying to add hooks for interleave-mode. But personally, I think defining an interleave-mode minor mode maybe is not really necessary. Thanks !
