I would like to see this as well. I have a lot of folders with email that I do not need to fully synchronize. One program that I use quite a bit is EssentialPIM (both Pro and Free) I can choose what to do with my folders. I especially like EssentialPIM’s synchronizing features. I can download messages, headers, not synchronize at all or hide the folders completely. I would really like to see these options in emClient. It’s a great product… but it could be even better.
