I think it would be really nice if it was possible to stop a line of code from being executed when I'm making a CSS document. I have seen this feature in other editors and can see no reason why WB2014 shouldn't have this feature also.
I have made this small illustration so you can see what I mean and besides an images says more than words:
Explanation: the line with the stop sign won't get executed - the stop sign will appear when the mouse pointer hover before the code.
I'm interested to know what the devs think as well as the rest of you ? - my suggestion don't apply to CSS only but also to the rest of the supported languages.
