Hi Mark
When i read the thread relating to this, actually i think what has been suggested has:
1. Been misunderstood
2. Been acted upon without really seeing the risk of making the change
3. Been incorrectly applied
This is what is said at 5:41 PM Friday, 31 March 2017 # 5
1. You need a bigger and red Exit button - that is named Exit! The exit must be more obvious/intuitive by users. Why dish the red X on top right?
2. Get rid of the "Are you sure you want to leave this - SITE(!)" pop-up. At least re-phrase it to "Are you sure you want to leave and go back to your site/blog?"
In actual fact, i take from point 1, that by making the button red and naming it EXIT, you are making it really clear that you are Exiting Edit mode (which naturally comes with the risk unsaved changes could be lost)
With point 2, the person is saying, the problem is with the wording of the pop-up.... it suggested you are 'leaving the site', when the user is really just 'closing the authoring screen'. That's why he suggested the wording change to '...go back to your site/blog'.
I really think this either needs a clear warning for users that by hitting the back button, any unsaved changes will be lost. I envisage many user complaints.
Kind regards
Paul
