One of my main use cases for Evernote involves sharing notes on a consistent basis.
Previously, sharing a note was part of the chat function. This was useful, since people could see when a note was shared with them in chat and quickly follow up. Also, the ability to add a chat message during the share process was convenient as well.
Now, there is more confusion about when notes are shared — especially if shared notes are moved between folders. Would love to see the sharing notes process reincorporated with the chat functionality.
