If you just smother the resistor in a solder blob, this melts both sides at the same time and it pops off quick and easy. I would only do this with solder mask in place, but that is the norm with SMD parts.
I was not planning on ordering just one 0603 resistor, they are 100 for $1 on a popular auction site. With electronics I pretty much always buy way more than I need, the stuff is so cheap and it takes forever to come from China so I like to have a stash of parts. I have it in 0805, but of course they used a different size.
I did consider a potentiometer, but I will have to decide where the screen will be mounted before I add that, needs to be well anchored so it does not put stress on the pads.
