This looks great. Two things that got me though...

The "picker" tool does not do what I thought it would. And for the modifier classes I'd rather see the word than the color if I had to choose one of the other. I.e. "danger" instead of a red square.

One of my favorite things about bootstrap is the way class naming is semantic -- it denotes purpose not color. So using a color picker looking square to change the modifier seems non-intuitive to me.

What did you except of the Picker if I may ask?

Given the icon I expected it to do something with color. I don't know what given the context but the only time I have ever seen that icon is for color picking and usually not in a way that modifies my clipboard.

Okay I get your point. I noted it for improvement.
