Leaving a playlist with unsaved content now asks first
Leaving a playlist with unsaved changes on its Content tab asks you to confirm, so the items you added and the order you set are not lost to a stray click.
You will not lose playlist content to a stray click. Add, remove or reorder items under Playlists > a playlist > Content, and if you leave the playlist before saving, Screenly asks "Leave without saving?" first. Closing or reloading the tab gets your browser's own warning.
