I want to use QT Creator but I find some things frustrating such as finding out how to change compiler options in a reliable way. Sometimes it is QMAKE_CXXFLAGS or some other option in the .pro file. In every other IDE it is a tick box in project settings. Yes yes I know a tick box sucks but it sure makes things easier to remember how to do rather than yet another cryptic bit of text in a config file, I have enough of that anyway.
