If you've decided to retire the QML Support plugin, it might be a good idea to update its description over at JetBrains as well, so that it'll be clearly indicated as being "Deprecated" or "Unsupported" or whatever in the Marketplace interface of their editors.

Right now in IntelliJ IDEA, for example, there's no hint that it's no longer supported:

Thanks!
