Projections are important, and, once we get them working robustly, will be a key abstraction of our platform. Currently, when viewing the info page for a component, I get no indication whether a particular input is a projected input or not. This needs to be made clearer, and maybe not only on a port basis, but perhaps even on a broader component basis it should be clear if a component uses projections or not. The reason for this is that projections will allow for maximum interoperability, so one of the first questions I want to ask as a user browsing the store, who is faced with multiple choices for a given component (real example, there are two scatterplots in the Explore page), is "Which of these use projections?" because I want to use the one that does.
