no, i didn't change the UI, mybe i will...
here is the link for resource hacker

...and, some more tips... when changeing resource files (in this case bitmaps or *.bmp files used as an icons) you have to make them same size, one way to figure the size out is to save the existing *.bmp file and open it in xx to se the measures, and the background color of the *.bmp must me the same (the ugly pink one - the one that noone would ever use) ;-D
that's about it...
using resourcehacker you can edit the dialogs too, text on context menus, buttons, windows, you can change the buttons etc...
just play around with reshack and you'll figure it out...
