Ability to customize columns in list view

I would like to be able to add or remove columns in list view (show door code in a column, etc.) 

Would also like the ability to Save Views. want to setup a list view with particular columns and then recall it at a later time. ait a waste of time to continually setup a view evrytime you want to filter contents. This seems to be standard on almost any web app where list of contents are recalled from a database.
