Yea!  An officer vote for KTH! :)  I have both installed now and found that I can disable one of them and use the other when needed.  So as long as I don't find out one or the other is being a resource hog even after disabling it I'll probably leave it be.  Should I ever pug 5mans again (/sigh) it might come in handy.  Of course, it's a bigger pita to keep two addons updated as opposed to one so we'll see...

KTH (KTM?  Whatever it's called..)
/disable
/enable

Omen
/toggle (enables and disables)

I noticed the author of Omen did indicate he may make the addon compatible with KTH again at some point, but nothing set in stone at this point.  Anyway, I'll make sure KTH is /enable on raid nights!  :)
