This extension allows you to revert to the default settings of Automatic1111 Stable's Webui AUTOMATIC1111's stable-diffusion-webui
This is how my customized UI looks like. You first go to the tab called Default settings
You press the button Reset settings and afterwards this appears in the textbox :
'Settings are resetted, RESTART REQUIRED'
Which means ,it worked, you need to restart the Webui.
If for some reason you don't like the look of the default webui , you can always go back. place the config.json and ui-config.json located in
/extensions/Reset-to-default-settings/scripts
