This is an often requested feature so we’re considering it for the next version of eM Client. I’ll change this topic to “Idea” so other users can comment it.
Great idea! I was just trawling through the forum to look for something else (custamisable shortcuts), but this is one of my use-cases and I’d love to see the feature implemented!
I guess it’s not in this version, also after the upgrade I don’t see my list of email addresses in the left sidebar, my contact sidebar is empty too, no calendar list also…!!!
