I used to "Beta Test" but it was just a mad rush for a few days, there was no way you could try things out and give development feedback on things. The last time I was in it I said about jail windows that they restrict you too much but it didn't get implemented until yet another year. I would prefer a back n forth approach where you can give feedback and ideas that are then implemented without waiting a year at a time. The more feedback that is given by users the better. PG don't always get things right if it's just left up to them, you need the constant feedback > development, not a year in between.
