Inspired by a discussion with u/ArcherJones1985 (Check out their version here)

This tool is a modular multi-ksampler workflow for the purposes of testing schedulers and samplers.

In it all steps, CFG, and seeds are unified and the ksampler subgraph is limited to only changing the sampler and the scheduler. It also includes a labeling node built into each ksampler (though I didn't bother to break out the color and position settings into their own thing), as well as a 10-image stitching ksampler. It also has a lora loader built in (with more of course being possible).

This is made for Z Image Turbo but I don't see why it wouldn't work for any other model.
