(Not a huge issue for those of us who understand views, but might help some newbies):
When creating a new view, if I am happy with the default settings from the "add view" page and click "Save and Edit", I am brought to a new screen, but there is nothing to suggest that I don't need to save the view in this new screen, or any button called "Save" just in case I do.
I looked around a bit, then decided to add "something" to "see what would happen"… then a "Save" button (and helpful notice came up on the screen).
Perhaps this helpful notice could display at all times:
if I don't need to save: "All changes have been saved"
if I do need to save: "Changes are stored temporarily …"
