In general I would prefer to always show the full output of a command, and in a majority of usages have to manually select this checkbox to see the output.

It would be nice if this can either remember the last state of this checkbox, or an option were provided in the application settings somewhere to enable this by default. This is particularly true where a command fails in any way - another option might be to expand and select this if a failure occurs.

Perhaps there's a reason I can't think of why this checkbox is not enabled by default or persisted - is there a security concern behind what might be shown in a message?
