Two of them are not interactive.

I see.  I'll update my install.

What I meant was that I want the bookmarks to be highlighted as soon as
I visit the file.

Yes.  I do not intend to use bookmarks very heavily (i.e., not too many
of them), and I'd like them to be highlighted by default, without any
explicit action.

Yes.  However, this seems to be a tautology: I'm *always* in the
"current buffer"!

Also, I want to use bookmarks to, well, mark places I consider bugs, for
instance.  I'd like to *see* them even when just scrolling through the
buffer.

Thanks again!
