Lua is a programming language originally designed for extending applications, but also frequently used as a general-purpose, stand-alone language. It combines simple procedural syntax (similar to Pascal) with powerful data description constructs based on associative arrays and extensible semantics. It is dynamically typed, interpreted from bytecodes, and has automatic memory management, making it ideal for configuration, scripting, and rapid prototyping. It is implemented as a small library of C functions, written in ANSI C, and compiles unmodified in all known platforms. The implementation goals are simplicity, efficiency, portability, and low embedding cost. It has been used on games such as World of Warcraft, FarCry and Angry Birds, among others.
I know you guys have put a lot of effort on the new look & feel, and I do believe things have improved underneath. However, I have to agree with Sven: IMHO there are some usability issues that should (could) be reworked. I think the old black background behind the app name was more eye-catching. Also, another disadvantage of the dropdown for the choosebox is that we're now unable to open a product homepage on a new window -- this one I do miss a lot.
Well, just my $0.02. I'm sure all that has been done has been driven by the best intentions, and I'm grateful for that. Some layout issues are, at the end, a matter of taste, it's just a matter of getting used to that.
