I am glad someone is putting in this effort. Many years ago, there was another project called GIMPshop to make GIMP's interface more accessible to Photoshop users.

They taught Photoshop at school, so I found it easier to use GIMPshop than regular GIMP.
Looks like the last release was from over a year ago and the issues indicated it no longer works with the latest GIMP release.
That's actually what I thought this submission was. Didn't remember what it was called, so I didn't realize PhotoGIMP wasn't GIMPshop.
