One of the biggest problems with GIMP and Inkscape is how GTK renders numeric inputs. Look at the size of those +/- icons on the toolbar. For drawing software with lots of numeric inputs, that means an insane waste of space. Proprietary software like DaVinci and even Photopea have much smaller inputs, allowing them to create far more complex GUIs and featuring without cluttering the window.
