Whats that faint image in the lower-left hand corner of the splash screen?
It’s a watermark of one cell of the periodic table of the elements. Instead of version numbers (like 1.0) XWT releases are named after the elements, in atomic order. The first release of XWT was Hydrogen, the second will be Helium, and so on. The watermark in the corner of the splash screen lets you know what version you’re using.
