What are some useful tools that /hgg/ genners use?

Resolution can impact the composition of an image, the exact same prompt and seed can turn out differently depending on the resolution. Therefore it can be worthwhile to experiment with different resolutions and see which iteration of an image turns out the best.

I use the extension Random Resolution: https://github.com/IkariOkuto/sd-webui-RandomResolution . That lets you set a series of different possible resolutions and chooses one from the list when it gens. It results in a much wider variety of images than just using a square resolution like 1024x1024.

Pic related is an example grid using that random resolution extension.
