Hi Maysky, try CustomUI (one word no spaces) with Keywords target: "Titles only" to find the CustomUI post, and for GUI Builder put in "GUI builder" in quotes, also Titles only.
Hi Maysky, well they do different things. GUI Builder is for changing colors of the UI background and controls and Max's CustomUI is for adding in some buttons on the bottom toolbar.
I don't think there is any way to compare them since they don't do similar things at all.
