We're working on some things that may help in this arena. Also, though,
in case you're not aware of this, deleting a segment really only hides
it from the segment list; it doesn't actually delete it behind the
scenes. If it is used in a report or project, it will continue to
function there. Try it out and see how you like it, but this may give
you some freedom to delete old segments and keep your segment lists
tidy.
