Tagging Priority

[Morrigan]

It would be nice (and I understand complicated) if when you're tagging someone that the people that have replied to the thread get priority in the listing.

So if say I, Matt, Morgin Brandon, etc all posted in a thread when I type @m Myself, Matt and Morgin would should up first above the user "M" or other alphabetical options. Basically giving people that posted in the thread a little more weight and make them easier to find.
