Feature reqest: Adding img2img feature

[Mnkai]

First, thank you for maintaining this project, this project is really interesting. I spent a whole day trying out various stable diffusion prompts with this app.

One thing that bothers me is small imperfection from the output images. I believe running the txt2img output result through few img2img cycles can improve the result significantly. Do you have any plans to add img2img feature to this app, or maybe including a img2img binary inside the app without GUI to allow power users to tinker with the original program without setting up the painful development environment?
