help(functionname) in Python should have a flag that permits a pop-out that links to thorough documentation of that function to provide better functional parity with the Python window in ArcMap.
ArcMap has a useful panel that shows valid values for each parameter of the function. The help(function) in Pro obscures the recent python function history and results in the console, which hinders efficient use of Pro's python window. I would prefer the panel be available in Pro, but BUG-000116756 was declared not in production plan.
