Your program is excellent overall. However, I noticed an issue with (unsent) draft email: the count indicator disappears from the folder after the email is/are automatically marked as “read,” even though it is not yet sent. This is an incorrect behavior because the draft boxes should always indicate the total drafts pending - users assume that this is what draft folders are for. Also there should be a way to save as draft directly (instead of going file/save).
Thanks (I own a pro license btw).
