Is there any plan to improve existing definition? there are lacks of some documented functions which we can use in plain JS. I just started to use typescript and can not see proxy objects, getTextSize on html interface, data on list|datatable class etc. I can extend interfaces, use some hacks, but I don't think it is the right way. Also I wonder, why config interfaces are independent and not inheriting a parent one? So if I want to extend textconfig, I have to extend all of its logical children by hand.
