Thank you for the feedback. I just wanted to let you know that we have started work on bringing the ability to Copy to another folder. I will keep this posting updated to let you know once we have shipped this feature out to everyone.
Again, thanks for the email@example.com commented
I used to be able to "move" OR "copy" emails to the folders that I created.
WHY has the "copy" option been discarded??!!!! That was INREDIBLY USEFUL!!
