Hi,
In lab 2 performance estimation, it seems not all function calls in the main.cpp can be set as root function. Only the ones with small "S" letter on the upper right of the green dots ahead of the function names were displayed in the "select root function" window, if it is possible to select any function we want? And once I set root function from main to others, I was not able to see the main function in the “select root function windows” again in order to change back. Is there anyway to set it back? Thank you in advance!
