UNO API Reference should have an own subdomain
http://api.libreoffice.org contains an overview of several ressources. The UNO IDL API reference is hosted at http://api.libreoffice.org/docs/idl/ref/index.html
It would be nice to have quick access to the UNO IDL reference via an own subdomain, like uno.libreoffice.org or something like that.
The same could be done for the Java and CPP api (cpp.uno.libreoffice.org and java.uno.libreoffice.org)
