Currently there are two custom button types available to table views: button on each row, and checkboxes with a button above the view. Both operate on individual records.
Can we have a button type that is placed above the view (like the one that comes with checkboxes), and meant to be applicable to the whole view?
Buttons of this type can be used to set filter conditions that is applicable to the whole view. This can be made to do two types of actions:
1) Call up the "Ask the user" settings (and the "Ask the user" UI doesn't need to appear automatically when the view opens). Besides, currently the "Ask the user" settings don't seem to be useful on child views of a "record preview". This new button type would be very useful on child views.
2) Call actions to build more complex filters on views that can also be saved and persistent per user.
