thanks a lot for your feedback about the feature test page.
Unfortunately there is nearly no feedback nor test results for weeks on this page even most of the features are in features.opensuse.org.
You are right, there are features that are not that clear which are not access able via features.oo. This is due to historical reasons, and cannot be changed that easily.
So please focus on the clear and access able features if you are open to help.
Thanks a lot for your efforts.
Best wishes, Holgi
