Amazingly, this little tool is perhaps the one I use the most. Next is the alignment toolbar. But then there are probably many other such tools that I simply don't use, because aSelObj() + intellisense is so much better. I don't even use the color picker - I pick my colors from a photograph, when I really need a coordinated set, and copy (or retype, depending on the tool I use) the RGB values.
