It would be nice to have the ability to give away (or sell) components as a bundle. This mostly applies to things like input components, and maybe certain types of visualization components. For example, I'm starting to build a toolbox of React based components. It would be nice to easily share all of those so if someone wanted to use them, then they'd just have to look for one thing in the Explore (store pages)...instead of looking for lots of individual components. Then as a developer, I could add to a bundle and they would automatically see them in their component browser in the xap builder.
Obviously this low priority and there may already be some sort of plan for this in the future.
This is a great point, and something that we're actively thinking about!
