I run a website, wycliffe.me, for redirecting traffic (URL redirector). But I need it to have a CRM sort of component to it. So I added some custom fields to the Posts using Just Custom Fields. (I am using Posts, but I could just as well use a custom post type Custom Post Type UI.) But now I want a summary of some of those fields in a special panel on the back-end. So I have collected some links to read and start hacking.
First I need to create an options page in the admin area: http://buildinternet.com/2010/01/create-custom-option-panels-with-wordpress-2-9/.
Next I need a way to collect the data. So I look for a plugin which can search my database and return fields…. sorta like views for Drupal. And wala there is such a plugin: Query Wrangler. (Query Posts might be another option, but I did not try it.) However, this plugin is not powerful enough. I can not search all the fields created by my other plugins, only my custom fields and content types. More power would be ideal.

Next I need to be able to see the widget in my admin area… so I need to widgetize my options panel. Here is where the Reading is a little fuzzy, ’cause I am not sure if many people do this. (Possibly indicating that there is a better way.)
