[Verifier] When using the verifier I can easily sort the results to filter them by signature and witness event

To be able to navigate the verification data better, it would be very helpful to have filter options and have a very nice compact view of all the verification data.

It would come in handy if I'm able to sort with an icon to display all signed revision and or apply an additional filter for all witnessed revisions which are also signed. Or only for witnessed revision. So all the different options which help to navigate the verification data.
