I don't know if this is possible but it would be a lovely plugin.
When playing in the moors, I play a lot as a warg at the moment, the one thing that bothers me most and that is really easy to miss in the heat of combat is when you're being tracked. Currently it's just a message in the chat-window and that chatwindow can move pretty fast in some situations. So that notice is very easy to miss.
Would it be possible to make a plugin that analyzes the chat-window for specific strings of text and then gives the player a popup (preferably with an editable message)?
This could have several other uses as well as long as you made it a very generic, simple plugin.
* Spordo Rumblefoot - Hobbit Minstrel
* Tiebain - Gondorian Hunter
* Rhuchgruz - Warg
