@L_Churchill Great new content! By the way, The custom widget page could use more precision on various topics: - _Importing/Exporting Apps_ =\> wrong title? - More information about execution model: is it single or multi-threaded? - API documentation: is there any other function besides getValue, setValue, fireEvent? Also, does any of these function block? is async supported? - Libraries (d3 etc.): how to call them? - What value do uninitialized variables have and when does that happen? - Read-only properties: I guess its the widget and not the app that can only read but it would be better to clearly state it. Also, what happens if we call setValue anyway? - How are Tulip types mapped to JavaScript types? Some are obvious/probable (Text =\> string, Number/Integer =\> number, Object =\> object, Boolean =\> boolean, X List =\> array of X, Datetime =\> Date) but not others (Color, Station, User, User Group, Machine, Interval, Image URL, File). - Does Tulip guarantee to call at least once the getValue(‘foo’, () =\> {…}) of each property (even if the property is initialized with a Static Value) when the widget is displayed for the first time? ---

Hi @fti , thank you for this input! I’ve started circulating these questions to our team and will make sure these things get documented.
