Fizzwidget TrackMenu 

According to my psychometrician colleague, the average adventurer can only hold in his or her head the working knowledge to perform (or use) seventy or so skills (or items) -- on short notice, that is. Those who have time to consult their spellbooks can recall and put to use anything they've ever learned... but that's little comfort if you find yourself in a Devilsaur's belly because you couldn't remember fast enough how to Track Beasts. And the more one tries to keep in this limited working memory ("action slots", the expert calls it), the more easily distracted one is by all the clutter.

Enter Fizzwidget TrackMenu! This handy device attaches to your current navigation equipment and keeps all your tracking skills at your fingertips, without undue confusion... leaving you more room to keep other abilities or items readied.

Features:

• Mousing over the minimap tracking icon (the part of the Blizzard default UI that shows which tracking skill is currently active) will show a menu of the tracking skills you have. Click a button in the menu to switch to that tracking skill.
• If you have tracking skills but none are active, the minimap tracking icon will still be shown, with an "X" icon (so that you can still use the menu to pick one).
• Unlike straight ports of older tracking menu addons, Fizzwidget TrackMenu is built from the ground up for WoW 2.0 -- it works the same regardless of whether you're in combat.

v. 2.2 - 2007/09/25

• Updated TOC to indicate compatibility with WoW Patch 2.2.
• Track Humanoids is now always in the menu for Druids (though it won't work if you try to cast it while not in cat form).

v. 2.1.1 - 2007/07/20[list][*]Refined behavior of the tooltip shown when mousing over the minimap tracking icon (with Blizzard-provided tracking spell info and TrackMenu instructions):

• If the menu is set to show on mouseover, the tooltip won't.
• If the menu is set to show on click, the tooltip will disappear when moving the mouse into the tracking spells menu or shift-clicking to get TrackMenu's options menu.
• There's now also an option to keep the tooltip from appearing at all.

[*]The invisible frame we use for opening the menu on click or mouseover is now at the proper depth; the menu should no longer open unexpectedly when clicking/mousing over frames (e.g. bags) that obscure the minimap.[*]We also make sure said frame moves appropriately when the display resolution changes (or you switch between windowed and fullscreen); the menu should remain useable in such cases now.
