Again, I might've just missed the feature (I really, really should RTFM!), but I haven't immediately spotted a way to attach arbitrary files to a project.
It would be interesting to be able to add arbitrary files to a project, could be photos of finished product, whatever. But, really, I am thinking about adding source files and documentation that go along a microcontroller project, so that public projects can immediately be used by anyone using EasyEDA. Get the hardware design and software from the same place!
Brand new interactions and interfaces. 
Easy to use and quick to get started.
