Tool bar placement (especially adjustment brush)

I accidentally click on that tool all the time when all I want to do is use the b+w / color options or select the radial tool. 

Please space out the tools a little more. They're too cluttered up there.

Not to cluttered up for me. I have never accidentially selected the Adjustment brush when trying to select the B&W option or anything else.

So you can't select the B&W option next to Color in the treatment area without accidentially selecting the Adjustment brush? You need better cursor control.

Maybe buy a mouse instead of using the Trackpad?

There is a large space between those 2 things with the word Basic in it.
