Proposual: more clear visual appearance of modifiers stack

After some working time with modifiers, I found myself that it really hard to fast understand which one where is started/ended [when they all opened], when you have a fast look. So it have just some times to try figure out and find needed modifier, each time. This some sort of example in mockup, but I dunno, maybe will be better another solution.

Updated to coment Lordvigore. About colors. I think it really good idea, but will work good only with default color sheme. So to avoid this maybe will good give flexible ability (like on the last optin in exapmples) When user might choose any color manually and at once put button/switcher 'autorandom-clolor' (I'm not sure thet for random botton good place there - meybe better in 'Preferences' menu )
