I’m also working on making the necessary changes for it to show under Save As…. As matthewkoverton noticed, Photoshop only lists the plug-in in Save As… for single-layer documents, but it appears to always show it under Save a Copy…, so going to Save a Copy… is a workaround for now.
Hi all! Main developer here - so far as I can tell, something changed in how Photoshop 2022 decides which file formats to list under Save As… and which file formats to list under Save a Copy….
