Crit recorder?
 

I saw it on a screen shot a long time ago, but never really thought about it. Is the a add on that tels me the highest crit for my spells and melee?

i just installed Scorecard last night and i quite like it.

there are also a few others out there...like TopScore_Fu or (far more complex) Recount...

TopScoreFu, Critline, or Scorecard.

I like AzCrit. It's hosted here.

Critology is good as well...the best thing about is that it shows the crit records in the spell tooltip
