I’m looking forward to shared pots for saving. It would be even more awesome if anybody in the pot could spend directly from a shared pot, or even associate a completed transaction with a shared pot. Then me and my girlfriend could put money in to a shared pot and we could keep track of how much we spend together.
Perhaps the option to allow anybody in the pot to spend could be optional. It depends how much we all trust our friends! At least there would be a record of it. A summary of how much each pot member has spend might go down well too in that case.
Did someone say feature creep?!
