Hook request for Web>Page plugin "additional info" display
In the Web>Page, Columns view, each tt_content element of type "list" (plugins) are displayed with the text:
Extension: <plugin name>
CODE: <select_key field content>
The select_key is not being used anymore by the majority of extensions, which now usually opt to use pi_flexform for storing setup configuration. So it would be nice to be able to display some other information instead of "CODE:".
The proposed hook provides enough flexibility so that extensions can display whatever they want on that place for their plugins (some setup from flexform, maybe even a list of records which will be displayed, or whatever else might be interesting in this overview).
