Theme approach proved to be unsuccessful as it took too much effort to keep it in sync with the rest of the application, while offering almost no additional value.

For example, in last few years we added about 20 new fields to the program, including some pretty complicated stuff like collaborations or custom field system. To support all these new features, every theme needed update, and that's really a deal breaker.

So we don't encourage using the obsolete themes anymore, because they don't support essential OrangeCD features. Eventually they will be removed from the website. Of course, any customizations to standard Default V6 theme, or any custom-made themes will still continue to work for the time being!
