The original reason for developing TF was to provide regular expression
matching in specific parts of messages. But once I finished the "easy" part
of that, I found that it worked pretty well, and there are a lot of other
possible filters that seemed to be more likely to improve the filtering.
So, it's stayed on my Wish List. I've got about 7 or 8 good ideas to work on
next, and its hard to say which ones would be the best choice.

Right, but of course regular expressions aren't the easiest thing to
develop. And they take a significant amount of time to execute if
interpreted on the fly. One of the reasons TF puts (most) filters into the
registry was that I wanted to be able to store a "compiled" pattern in order
to cut the runtime of the program. And it would need fast access.
Anyway, this is one of several ideas for improving the text filters. Along
with full word matching, and spam-alike matcher, which would be aware of the
most common w-a-y-s s pam mer s h1de w0rds.
I'm going to poll TF users for suggestions, but not until I've tied up all
of the loose ends on the new TF.
