I'm currently LF a mod that deals with Achievements. Specifically, I'm LF a mod that allows the following:

Hides/Shows/Removes the date stamp from Achievements
Hides/Shows completed Achievements within the default browser
Allows general customization of Achievement frames
Includes a search function for the browser and potentially a weblink to WoWhead for each achievement (I'm thinking about the WoWhead function of the Loremaster Mod)
An ability to sort Achievements

Anyways, please list your ideas or suggestions for a current mod, or the development of an Achievement Mod. Thanks.
