Hey Jochen - no, there are no votes, and no transparency in that sense. Requests are generally acknowledged by the DT team here, who to me appear genuinely interested, often ask additional questions, but virtually never promise a feature. I feel without concrete evidence that a feature commonly requested has a greater chance of being implemented than one which appears to be an individual solution. But obviously there are technical aspects too.
We do know DT is working on a significant update to DTTG, although there is no public roadmap (a fact which has been discussed ad nauseam in the forum), so patience is required
