There sometimes are situations where operators will spit out an error, but it is ok, as I expect this error to happen.
One good example is the SyphonSpoutInTOP.
When there is no sender, it will give me the nasty Error simbol, even though it is simply saying that it is unable to open the shared texture. Which is to be expected in my usecase.
In programming we can catch this kind of exception and handle them,. but here to only way for mke to handle this would be to bypass the operator, which is more stress then I like tbh.
