Feature request: Different wizard configurations per content element

[saitho]

We have different use cases where we want to use the Focuspoint extension, which require different fields in the wizard.
Right now I don't see a way to achieve this without introducing a separate database field and copying nearly all classes and adapt for the new database field (overwriting the renderType inside the sys_file_reference (e.g. defining columnOverrides inside overrideChildTca) does not work by TYPO3 Core).

Can we add a way to setup field configuration in the wizard per content element?

mod.tx_bwfocuspointimages.settings {
	fields {
        _default {
          // default fields here
       }
       tx_myext_worldmap {
         // specific fields available only in focuspoints wizard of content element "tx_myext_worldmap"
       }
    }
}

Maybe that can be considered in the upcoming refactoring. :)
