How can I reset everything to original settings?

I've been using Ubuntu for years but am a complete newbie with kdenlive. I started playing with moving panels around, and have completely messed up my kdenlive configuration. I'd like to just restore everything to the way it was when I first installed kdenlive with Synaptic package manager. I tried completely removing the package, rebooting my Unbuntu system, and re-installing, but it still remembers all the panel settings. Is there some magic file I need to delete to make it forget all the bad stuff I did to it? The way it is now, I've made it completely unusable for a beginner like me. (Next time I'll know to save the original config as button "1", but it's too late for that now.)

I realize that another approach would be to manually drag each panel back where it belongs, but I haven't been able to find any examples showing what to grab, or even where one panel ends and the next one begins. When I look at the screen now, I'm completely lost.

I'm using kdenlive 0.6.0-svn because I have an 8.04 Ubuntu system and that's what Synaptic gives me.
