Dear Proton Mail,
I use a lot of labels to organize emails. Many emails have responses back and forth. By labeling them correctly, there is an overview of the route of emails.
Because more labels can be linked to an email message, I note that the labels are put in alphabetical order.
This is not entirely correct because the order simply doesn't make sense if you use more than one label. It makes more sense (to me and perhaps others) that the label order can be read according to the user's placed labels one after the other.
It's just an idea. Maybe you can do something with it.
Greetings,
Rob
