I just wanted to point out a couple of things about this plugin....
I notice that if my client copies & pastes stuff into the excerpt it is automatically surrounded by unwanted
If you want to see the excerpt code, you have to deactivate the plugin and go back to the page/post edit screen. It would be much nicer for the plugin to be able to toggle to HTML mode.
It does not offer any option to add an image to the excerpt :(
Hopefully these are things that can be taken under consideration for future development.
