Hi,
The current state of the UI in Knowledge Center is broken, imho.
For some reason, "All" always means all Safe posting first, regardless of relevance and creation/update date.
And if one chooses filtering "Ideas" or "Questions" (why not checkboxes to see both??), one always (and only) get them sorted as "Updated". If I afterwards choose e.g. "Votes", I go back to "All".
It used to work differently, if my memory serves.
Please fix this, or specify how to make it work (I'm using Firefox).
Cheers
