With the column selector box, I'm referring to the arrow on the very right of a column and/or list, which allows you to pick from a larger set of columns and pick those, you'd like to be visible.

Whatever is easier, please either style the arrow and the box it opens or remove it entirely. What speaks for removing both UI elements is that currently, we seem to show all columns in all views any way.

If you decide to style these features:

• choose a dark gray (#666) instead of black for the arrow opening the box.
• style the box so that it fits our design (use "tick" icon font, gray background and proper fonts)
