Chinchilla Minimap alters the Blizzard Minimap in a way to provide much nicer features and other niceties.

Appearance
Allows changing of blip size (useful since 3.1), border style, shape of the map (doesn’t have to be circular, or even square, lots of options are available), size, etc.
Auto zoom
Zoom out the map automatically after 20 seconds (or so).
Compass
A more flexible north-east-south-west indicator.

ZAspect, ZTrap, ZTrack, ZPet Spell button bars to save space. Hold ALT to Drag the first button. Key Bindings available for all buttons. Use /zhunter to access options.

ZAutoShot Casting bar for auto shot. Use /zautoshot to lock/unlock the bar for movement.
