Comment 57 for bug 1347305

First of all, I want to thank you for having an issue with the design *and taking action* on it, it's very much appreciated, and a rare quality. I actually am a fan of your idea, and think that if done properly, could balance the "cleaner design" without having such a radical change.

Valid.

That is being handled separately in bug 440377.

Noted, that would indeed be a separate bug though.
