My Clippings

I've said this before, but it'd be nice if all the clippings for each book were in different files.

It'd be nice if when deleting a book, it asked if you wanted to delete the clippings for that book.

You can open "my clippings" on the Kindle and highlight something in the clippings.  Does this seem redundant/circular?

If I go into a book and delete the comment I wrote with a highlighting, the highlighting remains.  if I delete the highlighting first, the note remains.  Shouldn't one delete the other?
