When I start coding a function/method call then I have to read the documentation to know which arguments it expects. It would be nice if the code editor would show an information bar (eg. at the bottom) which displays info about the current function.
For example, if I type:
var test = Class.MethodX(
It could show at the bottom of the code editor:
MethodX(value, length, [somethingoptional]) -> ResultType
