[Feature Request] Display next image for inpainting with a key shortcut and other QOL features.

[DoctorDerp]

I would love to see some of these basic quality of life features.

1. Display next image in folder directory for inpainting by pressing the > arrow key on keyboard or some other shortcut.

Currently you have to manually click the file directory every time which loads the displayed images and you then have to scroll down to the image you want which takes forever when you have hundreds of images, also for some reason the position of next image isnt saved, you always start at the top, so you have to scroll past hundreds of images every time you modifying a new image.

2. Toggle that when turned on will automatically save image after every stroke of inpainted masked area.

This would allow you to just blast through hundreds of images without manually clicking the save button every time. Alternately a save image shortcut would suffice.

3. Save image as png.

Self explanatory.

Thanks for all the work folks hope you guys can implement these!!
