One thing that amazes me is that to this day, its Layers palette offers no way to select multiple layers. At least, not through any UI convention used by major operating systems in the past couple of decades… Under macOS it also has this funny little issue of picking up on the most recently added input method for setting the UI language instead of the system's default/current selected input method. As a result my copy of the GIMP runs in Japanese despite the rest of the system being NA English.
