Add tab filtering and file type filtering to TCA-defined link wizard
Many extensions would benefit from the ability to simplify the link wizard. For example, when creating a record for a TemplaVoila Template Object, selecting an HTML template is the only reasonable option but the tabs for TYPO3 Pages and email addresses are still displayed. Likewise, its possible to select an image file.
The attached patch adds allowedExtensions and blindLinkOptions as params when defining the link wizard in the TCA. There is already TSConfig support for blindLinkOptions, so we're sticking with a common name.
The TYPO3 Core API documentation will need to be updated to reflect this change also.
