I made an Opamp PWM circuit example, took a while for me to click on to the problem in my circuit but I had the power pins reverse.
There seems to be 2 standard for opamp schematic symbol & the position of pwr pins. Wikipedia show the Gnd near -Input, most datasheets show Gnd near +Input.

What might be helpful is to add a + near the positive pwr pin when they are enabled. I am sure it will help others.(depicted in image attached)

Yes, you are right.

I will add labels to power pins.

Probably it would be helpful the posibility to switch power pins orientation.

Yes, that could be useful to keep circuit neat.
