I have a suggestion about Flags.
There shouldn't be Set ON and Set OFF, there should be only Set Flag... and also two consecutive dialogboxes.
First with title: Write Flag status (0=OFF, 1=ON) and Second: Write number of the Flag.
It's good for variable actions, less conditions is always better.
I agree 100%, however because the actions already exist, Clickteam's updating policies generally prevent them from being removed. Although they could remove them just from the menu and leave the actions for legacy code, I doubt it will happen.
It *may* be slightly possible that there is a small chance we might get an all-in-one action like we want. :\
