Thanks for the feedback. I didn't intend on turning this into yet-another-gui-plugin, but a fair few people have asked for these features, so I have put it in the todo list. I don't know if this will actually get implemented at this point, and even if it is, whether it will be part of 2D Toolkit or a separate addon. I can't say anything without carefully gauging the amount of work required, and how far I want to take it.
