Vhaerun Two more suggestions/observations. Please take them with a grain of salt, I'm not trying to be snarky....
1) While your custom developer/debug console does admittedly look very nice, it is beyond irritating that you've hijacked those commands from those of us already used to the default RenPy consoles you get with Shift D and O. You've effectively killed the use of UnRen for enabling the consoles, and your version of them doesn't really have "everything" available to view (and alter, if desired).
2) "Hiding" or obfuscating system variables in any manner is also exasperating. If, for example, someone wants to give themselves money, for whatever reason, they can't easily do so since they can't access the default consoles (#1 above), and you don't seem to have made that variable easy to find (for most people, at least; those who really know what they're doing will find a way to do it, but again, it just annoys your potential fan base).
