A "Create New Folder" button while inside working on an email would be great!
I like to categorize my pictures by email, for example by holiday or event - for our store. However, I will start an email, then go to upload images, and need to create a new folder. But, if it's a new holiday or event, I don't have a image folder created yet. I cannot create a new image folder while working on my email, in the Insert Image area. Instead, I have to log out of my email, go to the Library, create a folder, upload images either there or go back into the email. It's a bit of a time waster.
