I wasn't keen of the new design at first either but really it's not a major issue for me, certainly, when weighed against it's features, and sounds, not one that would make me give it up for something inferior.
It was done partly to try and reduce load on your system as loading images each time you changed kit did have an impact and BFD3 was less taxing than BFD2.
I'd actually wanted it to change the image each time you loaded a new kit piece and I'm pretty sure none of the others can do that.
