I've found another "bug" which is described as following:
for example i wrote the includes like this:
#include <string> #include <vector> using namespace std;
Then i noticed that i forgot to add <cctype>, and i want to add it between <string> and <vector>, so i moved cursor to the end of the first line and hit enter to produce a new line. Then i found that the header file "vector" was opened.
That is, hitting enter before the #include line will open the corresponding header file.
