Customizable views under the clients tab

This is a small request, but one that I would like to see. On the clients tab under the "View" drop down, you can select the various pre-determined fields for Client Status, Protection Technology, etc. I would like to see this view become customizable. I often toggle back and forth to find out varying information about a client.  If you could choose the fields that you want to display, it would make it much easier to view your information at once. Also, if you highlight (or select) a client, if you change the view, your selection goes away. You selection should remain when you change views
