Need more "loading" icons

Things like "Back to Pages" or saving a widget designer give no feedback that anything is happening.  So we're finding people are clicking them multiple times because there's no feedback that it's saving.

Dear Steve
As usual +1 from me since your request makes perfect sense. I for now know that even if the loading indicator of the browser tab is not showing any action that I have to wait a bit longer. But yes it would be nice to have a big fat laoding wheel turning and maybe the page grayed out.

Or if the whole thinkg would speed up so the user would not have time to click multiple times. Let's see what 5.1 brings.
