Fantastic! Rated 5 out of 5 stars
I love it!
I've been using ScreenGrab for a very long time but I always had to open up an external editor to add notes etc to screen shots. This just may be my new favorite add-on. Great work.
One thing though, Undo/Redo would be nice unless it's available and I'm missing it.
Thank you for sharing this with us all.
I'm already e-mailing friends about it.
