Can you go into more detail? I often wonder what issues people have with GIMP's UI.
There's no visual difference between "nothing selected" and "everything selected" - both show a marquee border. There's not even akeyboard shortcut to drop a selection (Select -> None) afaict.
When you paste something, it appears in a separate "layer" - even if you're in quick mask mode. Want to move that thing you just pasted? Nope! You have to select the layer move tool first. Oh ho! But now your focus is in the wrong window. Not that you can see that.
It's unutterably painful.
The complaints about lack of features (adjustment layers in PhotoShop are great, and I really miss the Extract filter) are valid, but I used PhotoShop 2.5 and even though the UI was too complicated even back then, it was at least one order of magnitude easier to use than GIMP is 20(!) years later.
