make List_page show data

I'm testing phprunner
I guess that there is a reason that data isn't pulled from database when you select a menu item (table/view) and see the list page for that table. My guess is to reduce calls to database. But this isn't logical for every one. Clicking a menu item, you would expect that some data records are displayed. Some people might not understand that they have to search for the data first. Could there be a default that trigger action "show all" when list page is called without paramters
How do you force show all for menu items?

Where should this be inserted (event?)
Can I manipulate $"tablename"_tablelink_attrs somehow?
