TYPO3 Core

TYPO3 has 3 different methods/places to generate preview links.

• Module „List“ → Table “Table Content“ → Button “View webpage”
• Module »Page« or »List« → Context Menu on Icon of a content element → Selection »Show«
• Module »Page« or »List« → Edit a content element → Button »Save and view page«

Only one of them, the »Save and view page« Button while editing items, is nicely configurable with TSconfig:

Configure preview link generated for the save+view button in Backend. This allows to have different preview URLs depending on the record type. Common usecase is to have previews for blog or news records, but this feature now allows you to define a different preview page for content elements as well, which might be handy if those are stored in a sysfolder.

This configuration option is very nice. It would be nice if it could be used in all places which generate preview links.
