A lot of times, whenever I need to use a function, I always have to search the documentation to see what the inputs/output of that function are.
It would be helpful if, for instance, if I write "secondsBetween(", I would instantly get a tooltip on hover with all the details for this function, namely, a brief description; required inputs and output.
In this case, something like:
"""
secondsBetween(firstDate, secondDate) calculates the absolute difference between the input values in seconds.
eg: secondsBetween(dateTime(2007, 1, 1, 1, 1, 1), dateTime(2007,1,1,1,2,3)) would result in 62.
