This addon will add a "Save" button to the Talent/Glyph frame. Clicking this button will save your talent and glyph choices to the zone or subzone you are currently in. The next time you enter that zone, a row of icons will be displayed representing the talents or glyphs saved for that location.
[Update] For areas that are used for more than one encounter, unless you were present for the kill, you will need to target the boss in order for ZoneSpec to know what boss you are on.
When you have six or less of the clearing reagent (Tomes of the Clear Mind, etc.), an icon will appear along with how much you have left.
Slash Commands: /zonespec, /zs
/zs toggle - Lock/Unlock the frame to position where you want it.
/zs clear - Clear any saved data for the current area.
/zs reset - Reset all data for the current character.
