Thank you for the confirmation. The assigned number for this case is
case=32921
However I wasn't able to reproduce your second problem. If I replace the constructor with 2 parameters, like
testclass(int param, int param2) {}
then I press ctrl+shift+space inside the parens of the initialization, and type "1, " then I get the tooltip and the second parameter is bolded:
1. testclass obj(|); // ctrl+shift+space
2. testclass obj(1, |); // the second parameter is bold
Do you get different results with these steps as well?
