First of all thank you for taking the time to do this and for your work. The tools have made some great progress in the recent builds.

I'm currently on FF 22.0a1 and I can't find the ability to dock the tools to the left/right. I know I used to be able to. Whether that option is present or not, I think that it is part of a bigger issue, customization. I would love to have the ability to customize the hell out of this, either from a gui or code
