Feature requests:

1. click and hold shows menu, in addition to right click
2. alt. slim view using single star and a number
3. make it a menu extra so it can be repositioned via cmd-drag
4. release the code so we can play with it?

Further specs:

item 1:
On mousedown, nothing happens until either:
- a drag occurs; then you star setting the rating by the star being hovered
- a few hundred ms have passed; then you show the menu and no rating change occurs
- the mouse button is released; then you set the rating to the star that was clicked

item 2:
- menu icon is just a star with a number, either inside it or beside it
- rating is set by clicking and dragging sideways in the "air" (like knob buttons in some audio apps)
- rating could also be set by using the scrollwheel over the icon (this could also apply to the current UI)

And that's all. Thanks for a great and well polished app.
