Hi guys, great work on the render Panel, can you please add Post Effects there too?
It would make switching denoising on (and off) easier 
That is the one for the viewport. Rendering panel would be the one for document.
Oh, did you separate them?
And if they are to be separate settings then I think the “render setting” shouldn’t affect the “viewport setting”… but deviating from KISS can be a can of worms and a lot of work for support down the line, so with out further knowledge I vote for keeping raytraced display mode controlled by the rendersettings only. (Personally love tweaking stuff but the teacher and the UI designer in me tells me otherwise 
)
