There is often a great deal of confusion about what the term WORKSPACE means in Painter. This confusion is supported by the common usage of the term workspace, which is not the same thing. There is also confusion – or lack of understanding about the difference between the terms Workspace, Arrange Palettes, and Custom Palettes. I hope this video will serve to add some clarity to these terms. Please let me know if this video helps. this information is applicable to Painter 12.2 as well.
