The only big thing I miss (and I miss this with Github too) is a way to prioritise issues. Yes, I get it, you can label things 10 different ways and achieve most of what you get from a priority system. It doesn't replace the simple ability to get a list in order of the most important things outstanding in order. I want it to be easy to generate a list of 'urgent' and 'high priority' where the 'urgent' issues are listed ahead of the 'high priority' and not ordered randomly.
