Hi,

It works for this "setting" and RE-"setting" but not for annotations
change nor renaming. Maybe "set" is not a good name. Why not "placed"?
As a bookmark in book?

You're right and that is why it should be clear that this behaviour is
for "placing" the bookmark only. Maybe other kind of modified field
could be add later... or the current behaviour changed along with its
documentation.

A fully customizable "last-modified" sorting might be a bit too much for
bookmark.el but trying to gather many modifications under one umbrella
could be better than just "placed". What others think?

For my usage, I prefer the "placed only" behaviour.

Yes of course. But in what I proposed, 'created would only be a possible
symbol for `bookmark-sort-flag' (or new name), nothing more.

I've read it. But I think that for the bundled bookmark.el having a
predefined set of sorting functions could be enough.

As for composability of sorting, I think keeping it to "one at a time"
could also be enough. And for users that need more there is Bookmark+
