Eevee preview settings

In large scenes shadow maps, ambient occlusion, SSR, and SSS often need to be reduced for playback, materials setup etc when using Eevee. While they are usually not needed for previewing it should be possible to easily set them to the highest possible settings for render.

Having to constantly adjust these settings between rendering and editing/previewing suggests there should be more 'preview' options as with samples , 'presets' as with Cycles and 'simplify' options as with subdiv and volumetrics. I imagine most of the check boxes ie. AO, Bloom, SSR etc could appear in the simplify panel. As well as shadow map sizes.
