Good news is that all of the points have either been fixed or are being worked on:
Staking is needed to secure the network. Alternative ways of claiming the rewards are being looked into, but right now if you don't want to purchase GRC to stake or don't want to wait for the rewards there are pools to turn to (this is true for every coin, be it PoS or PoW).
Exchanges have been contacted but we cannot force them to include us. Many of them also come with a listing fee so getting listed on all would become expensive. Do you have some exchanges where you think our presence is missing?
Superblocks have not been borked for quite a while now, right? 220.127.116.11 released in September last year. At least I haven't heard about issues since then.
Crashes have been a pain, I agree. Some were addressed in 18.104.22.168 and it will hopefully be more stable now.
UI is being redesigned right now, though it does not trying to create the smallest wallet window possible. However, now is a good time to see what information can be thrown out and what can be rearranged to improve the space utilization.
Poll title was changed.
