Question about modifying text in a window

[somerandomdude]

Howdy folks. I'm new around here, and yes, I DID try searching and reading readme's, but I'm still having some trouble. Namely, I'm not sure if what I'd like to do is possible.

First, is there a way to highlight specific words in a chat window? Like, if I wanted "danger" to be red, but all other words black, can that be done?

Second, if it _can_ be done, can it be made to be "generic" such that if I pass a file or something it will turn all words that match a word in the file red?

Third, is there any way to incorporate a user-defined plugin that doesn't effect gameplay per se? I know this sounds a bit sketchy, but basically if the above metrics aren't built in somehow, is there a way that, using xml, we could tell the everquest engine to run some external executable or script with string input parameters such that it returns a string we could then display in the chat window (or some other window)?

I know these questions involve are a little bit more than interface issues, but I don't really know where to ask them, or if there's a better forum to ask such questions. Many thanks!
