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!
