Ability to set a folder to 'Online Only' via the live.com website.
Any machine configured to sync with the folders should acknowledge this setting and exclude the folder form syncing on ALL connected clients.
Handy for large photo/video stores you want always online and NOT syncing to Laptops/Surfaces/etc..
When a new machine is being configured, currently you need to be careful and uncheck the folder you DONT want to sync. It should take this setting from live.com.

This is extremely important since more and more we are moving to the cloud. I See my local computer just as a backup but the source should be the cloud. We all have huge photo/video libraries which need to be easily shareable in the cloud, but do not fit on typical SSD drives. So I need to store them on a NAS but I want them in the cloud also, and I really don't want them auto-downloaded to my computer after I have placed them in the cloud.
