The Soft Proofing sub-palette (for PLv6.1) looks like this;
However, it’s somewhat confusing because some of the options apply only to Printing (such as Simulate Paper & Ink - and, I think(?) Intent … which the on-line manual refers to as Mode !) – and some of the options apply to both Display and Printing.
Presentation of this sub-palette would be much clearer is there were a mode selector at the top, with options “For Printing” & “For Screen/Display” … which then determined which options are included/excluded.
Like the Uniform vs Spot Weighted modes for Smart Lighting;
Edit: Another good argument/reason for this refinement is that it would emphasise the relevance of Soft Proofing as being not only for Printing.
