Improved preview mode
The user experience for previewing content has received an overhaul in order to make it clearer and more logical for the user if they are viewing saved or published content. The preview mode (session) is a global state in Umbraco, which means all tabs will either be in preview mode or not. While many of us have gotten used to this over the years it is an acquired skill (and taste), this should now be easier, especially for newcomers, with the following improvements:
Auto-close preview session
If you have started a preview session, this will now be automatically closed if the browser tab (or tabs) have been closed. This means you will no longer return to a site in preview mode from a previously started session. No more “Wait have I accidentally published this?????” moments 😉
Pop-ups when switching browser tabs
In order to make it clear whether you have started/ended a preview session, 8.10 introduces a friendly pop-up that asks how you want to view the content you’ve switched to.
