I agree that the redundent tags for *mli files could be annoying.
However, with emacs I just hit M-, to cycle through all matching
tags. So maybe you only need a key binding for :tn<CR> ??

     I would like add its functionality to otags, but I
     haven't yet figured out how to do it.  Even if I do, Taglet will still
     be useful and easy to understand on its own.

Otags' architecture is a bit complicated, it does not really
invite the uninitiated for hacking. To add your wishes to otags
you have to:

- add an option to the driver in otags.ml
- arrange that the new option will passed to camlp4
- declare the option in one of the camlp4 modules 
- program your wishes

There is a patch below with the necessary changes. The name of
the option is -mli-only-module.
