Adri; To clarify, JasperServer 4 has, as part of the application, a repository functionality in which theme files are stored. In this case, one can switch between different themes, immediately changing the appearance of the application UI. However, I think you are looking for something else: a place, external to any instance of the application, that stores themes made by the community, that you can download. This second thing does not yet exist, but I believe it will very shortly. Initially I think it will be treated as a new project within this Forge called "JasperServer Themes." Tim Sheiner UX Architect
