I think you need to change the interface to do something like InvokeAi

it’s not convenient to do generation and edit settings constantly need to scroll

reduce vertical space and take more advantage of the horizontal.
There are really no sliders that use the space where 3 or 4 could fit, also the impaint has options that you have to go to the configuration to change them and they are very used.

There are options to add sliders/elements from the settings tab with quick settings
https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Features#usercss also a page where you can customise ui, saved on updating. I'm sure people have good templates floating around, idk
The inpainting section is the only section that seems unbalanced, maybe you're referring to that.

yes, it is, but still I think it can be improved

inpainting , you could probably make at least a lens when drawing a mask
inpainting , and in order to change something you need to go up and down constantly
