Perhaps it would be possible to introduce a lightweight summary action (loading
no extra fielddefs).

Use case: creating (large) lists of links to detail actions. The links might
only need a title and an url. The needed information is in the main
<prefix>_module_<liseinstance>_item table I think.

Similar to the 'loadprops=false' option of Navigator.

If going to implement take care of the subsequent 'calls' via the pagination
links too please.

Thank you.
