What's your favorite features that's unique to your local AI image/video UI of choice?

I’m trying to build a wrapper around ComfyUI, Automatic1111 and Easy Diffusion that can trigger image/video generation with a small custom UI on top for job history, backend launching/stopping, prompt generation via Grok, image-to-video, backend health checks, and run logs. I know this isn't immensely helpful since most of the popular UI's have those features built in, but it's been a fun project.
