For an individual Gmail email from a thread, If we click the arrow to expand the from header it shows for most emails that it is in the “All messages” folder. That’s not really useful.
It would be more useful to see the labels that apply to that individual email. Use case: Not all my emails from a thread have the same labels applied to them. So for now it’s impossible to see which individual email has of one or many of the labels Mailspring shows at the top of the thread.
