I think, it would be helpful to implement this feature like in MS Visual Studio.
It means: When I stay my cursor on function parameter and press Ctrl-Shift-Space, the list of all parameters will be shown and the parameter under cursor will be highlighted. It is helpful while checking the function implementation/call parameters according to function declaration, etc.
Now when the function parameters are closed by ")", it is not possible to show parameters list and always the "last" parameter is highlighted.
Usually I write the function header/call only once, but change it many times during the project implementation (and I am not able to use this feature in this case).
I miss it a lot.
Thank you.
