For textreme 2 we went away from the programming side of things and more towards creative writing and note taking. As a result of that there is no config file like with the first textreme that is used for highlights, all highlights are animated, built in and are summoned using select symbols ( you can see them on the game page and in the highlights tab in the game ). Sorry about that, im not sure if we will be adding this feature in the future, ill send a message here if we do.
