Right now the only way to use a template is to create a new folder/list/task and then move the information from the old one to the new. It would be nice to be able to simply "apply" the template to the existing folder.
For example we created a new folder template for our client space and now instead of being able to apply it we have to create a new one and move all the information we have over. Which is slowing down our new folder launch.
