Known Issues

Sorting isn't working as well as I'd like.
Also you have to specificly bind a key to open the UrbanAchiever frame. It should be at the bottom of your binding menu, in the UrbanAchiever section.

Usage
/urbanachiever or /ua to toggle the options and help.

All the current /commands for the achievement frame will open the new one.

Shift-click achievements to track them, alt-click them on the tracker to remove them.
