Guys, the calculated styles are great, but the inherited styles along the cascade need line numbers for the respective stylesheets. This is a major factor for development and inspecting elements. Inline editing of the styles and elements and adding attributes on the fly are great features but if you don't have a line number on what css file then you're taking a big step out of the process, in fact it becomes a hurdle. Let me know if this is a viable request because I KNOW i'm not the only one out here asking for this and Firebug can be great but it_IS_Sooooo_SLOOOWWWW lately. Webkit is the better browser. Thanks!
Very good feature request! The Summary
I just changed the summary to something more recognizable.
