I created this addon because I could not find anything else for this simple purpose. The Horn of Winter spell has a very short duration (2 or 3 minutes) but it is very beneficial and is free to recast. I was often finding that I was forgetting to recast the spell so I wrote this addon to notify me when it was about to expire and when it actually does expire.
I plan to add future functionality/customization including possibly a count-down bar, the option to change when the flashes happen, what color they are, how fast they happen, etc...
Currently there are three settings:
/howt [2/3] - Sets your Horn of Winter spell duration, if you have the Glyph that makes your Horn of Winter 3 minutes please issue the command "/howt 3" and this setting will be saved on a per-character basis.
/howt flash [on/off] - Sets whether you will see the warning flash and the expiration flashes - I plan on creating a setting for both the warning and the expiration at a later date but this will work for now to get the addon online.
/howt text [on/of] - Sets whether or not the addon will notify you of pending expiration or expiration of HoW in the error messages at the top of the screen.
Please post any comments, suggestions, feedback, bugs as I plan to actively expand on this addon to include better functionality and possibly more features.
