Mechanism to star message only if thread isn't already starred?

[dbarnett]

I noticed that if I set up a rule to star a thread, it adds a star to every matching message in the thread. This is usually not the behavior I want because it drowns out some nice special handling Gmail has for starred messages in a thread (Gmail includes starred text in the preview snippet and doesn't collapse those messages in thread view).

Could there be a way to apply stars at the thread level, only if there's not already a starred message in the thread, instead of applying to every matching message?

That sounds reasonable. Notice that the script processes by thread, so I think it's possible to retrieve the information. But it may require some change around how action is applied.

May also worth to provide control over this behavior.
Do you think it's better to provide a global config? Or it's better to be a property of individual rules?

[dbarnett]

Individual rules makes more sense to me. Just needs a little thought about how to "spell" it.
