As Gerrit I want that editors don't edit content directly on the live website
Any user editing content should do so only in their personal workspace. After an editing session TYPO3 should give the opportunity to publish the new content to the live workspace.
- editing only affects the personal workspace of the logged in user
- on logout or closing the browser window, TYPO3 asks if workspace should be published
- publishing workspace overrides any other content of the live site (ie. no merge functionality yet)
