So, is this an app that bundles it's own X11, or is it using a Quartz/Cocoa backend for GTK?
EDIT: I downloaded it, and the app bundle doesn't seem to have an X11, so that's nice. However, upon firing it up, it throws up a splash screen in front of all other applications. Who still thinks that's acceptable behavior on a multitasking operating system? Also, the app quits when the last window is closed, which isn't how OS X apps are supposed to behave.
