I'm looking for something with source code because I'm a bit wary of using a program that's going to be scanning a lot of files -- though in this case it's for someone who is unlikely to be using a non-GUI solution.

My preliminary searches turned up a couple of candidates.

Are there any reasons to not consider the current incarnation of dupeguru or Duplicate Files Finder?

Appreciate some opinions (informed or otherwise) :)

1909 seems to be working ok here so far too.

The way the widget works is it displays a single random item (from your chosen section), and you can tap to move to the next.

Got it working here.  Nice that you can tap to move to the next -- there's no way to go backwards, right?

Initially I wasn't sure how to get the widget to display once its preferences screen showed up.  I think pressing the back key / button works.  Is that right?  It turned out that whatever the widget display settings were, I failed to notice the widget on the home screen  :P

You could use it for random words of wisdom instead of questions.

Are you a mind-reader?
