the text editor is ace, also has a themes function it grabs them from a json file(which is half-made) the already made one looks like this:

{
    "main" : {
        "CornerRadius": {
            "LeftUpper": 15,
            "RightUpper": 15,
            "RightDown": 15,
            "LeftDown": 15
        },
        "Background": "#",
        "topBar": {
            "Background": "#",

                        "FontWeight": "Bold",
                        "FontSize": 12
                    }
                }
            }
        },
        "scriptList": {

        }
    }
}

the loading themes is already coded btw, should I release it?
