How about the solutin I sent with mumamo-save-buffer-locals and dito restore? I suggested something like this (mumamo-save-buffer-locals major-mode) (funcall new-major-mode) (mumamo-restore-buffer-locals new-major-mode) There is however a problem with this and the major mode hook. Things in this hook might want to change some buffer local variables. I think putting the restore part first in the mode solves some part of the problem. For this to work however delay-mode-hooks must be temporary set to nil (see the sources for `run-mode-hooks'). I have no idea what delayed-mode-hooks is used for so I do not know if setting delay-mode-hooks to nil may cause problems here. > If Imenu needs something more complex, we could also have a second > feature which is more complex and less clean, and Imenu could use > that.
