See the screenshot of the aggregator EIP. Yes its the one with the most options.
We could probably re-order the options so they are more intuitive. So we have the completionXXX grouped etc.
Also we may want to reduce the length of the text input fields for some fields which often are only a small value, such as the completionTimeout, which is a timeout in millis.
I don't know a good way yo do this. We can add some annotations to camel-core in the model to give hint about sizes of input etc.
