Option to hide title bar which works exactly how Firefox's title bar option works.
Under the customize toolbar option, Firefox provides a way to customize their toolbar in such a way that merges the "Close, Minimize & Maximize" option's icons into the tabs bar section. After all, why to waste an inch of space just to say to the user that they are using Firefox when they do know that they are using Firefox. Removing that extra unnecessary notch is the first thing, I'm sure, everybody who knows does.
This trick is common these days. Most of the famous applications either roll this feature by default or at least provide an option in setting. Software like Chromium, VSCode, etc.
This lovely, magic & yet so the basic option is available in Windows, Linux, or MAC.
How about we bring this option in Gimp too?
There is a big empty space after Help where we can put the Minimize, Maximize, and Close icons just like VSCode implement under an option named "Title Bar Style: Custom".
We can even put the word, "GIMP" in the middle, just what VS Code is doing here.
If this feature is already available as an option inside GIMP, ignore my stupidness to not finding it even after Google search and tell me where it is.
