Thank you for this great tool!
Can you please seperate the entries hibernate and standbye? Or let me know the executeables and arguments for it? Thank you!

This review is for a previous version of the add-on (0.9.1-signed.1-signed). 

That's not possible without third-party utilities.
You can switch between suspend/hibernate as described here:
