great, but Rated 5 out of 5 stars

It's really a great extension. But, maybe it can be greater.
I drag to select and copy a word or some words, the original selected words are automatically released. If I want to do some other operation with it, I have to drag and select again. Can you offer an option to keep the selection and I can use Esc to cancel the selection manually? thanks.
