Absolutely love the Polar Coordinate Etch a Sketch! Is there any way to add windows with counters to indicate the current values for rho and theta? I think it would be helpful when making a design to be able to know what those values are.

Yes, easy enough to do. If you open the dev console (usually F12 or ctrl+shift+k or ctrl+shift+j) and paste in the following it should work:

p=document.createElement("p"); etch.parentNode.insertBefore(p, etch); disp=function(){p.innerText=`r: ${radius}\nθ: ${(angle*180/Math.PI).toFixed(1)}°`; requestAnimationFrame(disp)}; disp()

Of course if by "windows" you mean little decorative displays on the graphical design that would take a little more work.
