A lot of pages of features are still the page that where using during preparation of this feature. It's hard to now for the user if this feature is really implemented, if the implementation is really what is documented, and it add noise when trying to read it. Look for example at : http://www.ovirt.org/develop/release-management/features/storage/importstoragedomain/ It starts with: Today, oVirt supports importing ISO and Export Storage Domains, however, there is no support for importing an existing Data Storage Domain. So one might stop reading at this line, thinking it's a missing feature. Even if he continues, there is a lof of mockup, that confort him in the idea that's a work in progress. He as to check the 'current status' to know that is really implemented. But were the mockup updated ? They should be replaced with real screen shots.
