Diolinux/Photogimp ? reverse-engineered prompt

Build me a PhotoGIMP style patch for GIMP 3 and newer that makes GIMP feel familiar to Photoshop users right away. I want the tool layout rearranged to match the general Photoshop feel, Photoshop style keyboard shortcuts, a cleaner workspace with more room for the canvas, and a custom splash screen. It should also have its own app name and icon where that makes sense.

Please make it work for Linux, Windows, and macOS, and package it so people can install it by copying the right config files into their GIMP settings after opening GIMP once. Add simple install instructions for each platform, including a quick warning to back up existing GIMP settings first and replace the old files when prompted.

Keep it community friendly and free to use. If you need details about current GIMP 3 config behavior, look up the latest docs online.
