I find it very curious that there does not appear to be any tool in existence with which to create SweetFX presets. I find having to edit TXT files less than ideal. Anyone know if a tool exists or maybe is being worked on?

there is the ReShadeFrameworkMediator.exe in the last reshade release 0.19.x

I found one. It's called SweetFX Ninja http://www.nexusmods.com/witcher3/mods/224/?tab=2&navtag=http%3A%2F%2Fwww.nexusmods.com%2Fwitcher3%2Fajax%2Fmodfiles%2F%3Fid%3D224&pUp=1
