Description

In the Shader presets, instead of applying it, leaving and coming back to tweak it, a basic "Preview" button would make all the difference.

In this case, the X (Left) button is not used for anything, so it's natural that should be the choice for it.

Research direction

Start by locating the Shader presets screen and the existing handling for the X (Left) button. Trace how a preset is currently applied, then define the preview flow so the shader can be tried without leaving the screen; done when the button previews the selected preset and allows further tweaking.
