Mother of all xterms?

[Ken D'Ambrosio]

Hey, all -- I've gotten quite used to gnome-terminal and konsole, and 
they both work, but I admit I have a little bit of iterm2 (for the Mac) 
envy -- e.g., being able to search back through the log to a specific 
timestamp.  Handy, that.  So, my question, really, is "is there a really 
cool terminal program out there with lots of bells and whistles?"  It'd 
be fun to kick the tires on something new.

Thanks,

-Ken
