Can you, please, consider adding "Don`t show this message again" check-box in all system messages like this one:
-------------------------------------
Success!
The site has been saved successfully!
-------------------------------------
It would dramatically speed up the process.
We can see the success on "Nothing to save" button.
A lot of unnecessary clicks in between.
The only place where it would be wise to have alert is when we want to destroy a block (and there is no such an alert message).
