selective viewing/editing of fields

[bhanuvrat]

One of my collections has a couple of string fields along with a list field that contains a few thousand elements. When I open them for editing in mongonaut, it takes too long to load the list 2 -3 minutes when I don't even want to edit it.
Desirable features would be:

• ability to select the fields to be shown in the admin
• changing the widget used for showing a field in the admin
