Visually managing MongoDB documents and collections

I'm using MongoDB in a reporting system and have to delete a whole bunch of test documents. While I don't have too much trouble using the JSON-based command-line tools, it gets extremely tedious to have to keep searching for documents, copy-and-pasting OIDs, etc., especially from a command prompt window (ever tried to "mark" text that wraps multiple lines?)

How can I visually inspect the databases and collections, perform some simple CRUD tasks and manage multiple scripts in a proper window (not a command prompt)?
