Slightly more precise instructions when using this plugin with Photoshop (export/save)

[kangsterizer]

Precisely indicate how to save/export - took me a minute to realize Photoshop's Save as will not allow you to export to additional formats (neither will export or legacy export).

I agree that Photoshop's behavior in this area is not intuitive. IIRC the Save As dialog filters out formats that are not compatible with the current number of layers.

Save As works fine with a single-layer document, which is what I was testing with when I wrote that documentation. I am considering changing that line to read:

4. The plug-in will now be available as the AV1 Image item in the Open, Save As (for single layer documents) and/or Save As a Copy (for single and multi-layer documents) dialogs.
