The bulk of this addon is the work of Gello, most credits go to him. :) I have modified his great addon TrinketMenu and adapted it for use with headgear instead. Except for the auto queue feature, which I removed, the functionality is identical to that of TrinketMenu.

Are you an engineer? Are your action bars filled with diving helmets, mind control caps, lady-spying-goggles and who-knows-what? You need a hat rack, and you have come to the right place!

This addon will make swapping hats easier. It will display your equipped hat in a movable action button. Mouseover (configurable) the button to display a menu of up to 30 hats in your bags to swap.

- Swapping/Using hats
Click on the main frame to use the hat. You can also make a key binding.
Trying to equip a hat while in combat will queue it, and automatically equip it once you leave combat.

Click on a hat in the menu frame to equip it.

- Customizing Display
Move either frame by dragging its edge.
Scale/resize either frame in the options frame.

If you're having problems grabbing the edge of the menu frame to move it, hold down Shift while it's open and the menu won't go away when the cursor leaves the menu's edge.

For more options, find the hat icon at your minimap, or type '/hat opt'!

- Usage:
/hatrack | hat..
opt | config - Opens the options frame.
lock - Locks the frames from moving and resizing.
unlock - Unlocks the frames for moving and resizing.
reset - Resets all settings and positions.
alpha n - Set the alpha (opacity) of the frames to n.
scale main | menu n - Scales the main|menu window to n.
