I have been doing some work on the field_extract module, a few minor fix-ups most of which wouldn't be noticed and added support for the entityreference field. You can find this module here: http://drupal.org/project/field_extract
Someone I worked with recently has put out my "deeplink" module which allows otherwise hidden content to be made available on a specific trackable URL. My version was Drupal 6 (that's what I was working on at the time) he's doing the D7 upgrade, you can find it http://drupal.org/project/deeplink
But deeplink needs my Controls module, and that's a baby that needs explanation. And that explanation is available on the project page http://drupal.org/project/controls there's both a D6 and D7 version both written by lil ole me.
Briefly: Controls is an API module which provides a similar function to CTools plugins (they have a lot in common), but requires virtually no setting up and is much easier to use. Now I always say that to people but I did seriously wonder whether it was true, so for the last commercial project I worked on I didn't use Controls, I went back to using CTools plugins instead. I desperately wished I hadn't.
So I'll stick by my statement - I think Controls is easier to use and in some ways more versatile than CTools plugins.
However they are also more easily abused. It's something for developers working on an end-client's website. Anyway I'll let you be the judge.
