At the moment our focus is on the new HTML5 user interface that we are building. That is the reason that some of the most voted items are not implemented for a long time. This will change very soon after we release our first official version for this year somewhere in June.
The votes on the portal are very important for us. Big part of the roadmap that we are preparing at the moment is based on the most voted items.
All the best,
the Telerik team
