LR "I'm feeling lucky"

As a picasa user moving to LR I'm really missing the "I'm feeling lucky" button in picasa.

Basically it just let the software make a best guess as to what your image needs.

Was it perfect? No, but often it was quick and good enough.

I've been poking at LR for a while and can't find anything equivalent.

Am I missing someting? If not are there any free plugins that will emulate "I'm feeling lucky".

Googling I see Topaz Adjust has a "lucky" button. Has anyone used that and how does it compare to picasa's implementation?

Thanks!!!!
