We use MJML to create numerous types of email newsletters, etc. It would be nice to have a feature where we could group mail templates together into a folder to be able to organize by campaign. Once there's about 25-30 emails that have similar look and feel (aka thumbnails are similar), it becomes time consuming to read the little project name. Folders would help greatly!

Also a search field that searches for either folder group name or email name would be awesome and speed things up a lot, especially when templates are shared across a larger team!
