Improve the breakpoint selectors (also known as media query selectors). Convert them to a row and optionally move them to the top bar.
If styles are applied to a breakpoint, a green indicator will be highlighted. To clear styles for a breakpoint, right click on it to reveal the red "x" icon. Click that icon to clear the styles.
Show all of the breakpoint boxes with indicators either (1) below the id/class selection input or (2) in the top bar if that setting is also enabled. Note: To clear styles from a breakpoint, right click on the breakpoint to reveal the "x" delete button.
Expand the breakpoint box (if not already enabled) and move it to the topbar for quick access.
