It's all just point of view.
Everything you do in basespace/battlescape is a pause.
"Alert on new UFO sighting" and "Alert on UFO landing" are completely equivalent for me.
Or should I make also Alert on new UFO optional too?
And there's dozens and dozens of such examples.
And they are all implemented for a reason.
Anyhow, I will make the option... but to be honest, the option will make the feature only
more prominent than it would otherwise be.
Without the option, the user would have to magically discover a shortcut (probably Ctrl+click on Tail icon or something like that), which is extremely unlikely.
With the option, the user will know it exists, and will be asking around until someone tells them how to do it.
