from the feature list you have, you have almost all the features i have been looking for from one combat log monitoring addon for some time.
the only other major thing would be nice is the ability to click target names (in and out of combat).

i know this is hard to do. but from what i have been able to gather, you make secure buttons while out of combat.
that allows those buttons to be click-able in combat, and while in-combat, create unsecure buttons to display additions to the watch list
(that won't be click-able until they are converted to secure buttons once you leave combat.)

I have used Paranoia:EPA for a while now.
but its click targeting is solely from unsecure buttons, preventing you from being able to click target in combat.
but maybe you can get some ideas for other features from it.

The author has been intending an extended total addon rewrite for a while now. but the current release still works.

another that has good features but is intended for Arena is Proximo. I havn't been able to test it yet myself,
but from what i understand it works something like my description above. except using Arena ID's to target.

i hope all this rambling makes some kind of sense. I'll be trying your addon out when i get back to my personal computer.
