nice, but limited, doesn't address my issue Rated 3 out of 5 stars

It's nice, but doesn't address the issues that are of importance to me.

If you could extend the Regex find to:
1) the find function on emails during composition (very important), and
2) (less important) find in "Search Messages"
... This would be killer.
