Lets talk about bitcoin which features would you like to be implemented?

I don't see any reason to introduce major changes.  Thankfully, Satoshi and the core developers have designed a great system already.  Only minor changes, mostly related to further securing and solidifying the protocol, are necessary IMO.  Unless a major fault is found with the core protocol, then no changes are needed.  All 2.0 services can be built on top.  Avoiding unintended consequences of protocol changes such as what happened with the March 2013 fork should be the highest priority.  Leave experimenting to testnet and the alts and if a major change is deemed absolutely necessary, then reevaluate.

Agreed however the March 2013 fork was due to an implementation issue not a change in the protocol.

The Bitcoin network is hard to change, and that's mostly a good thing, but it also makes certain upgrades very hard. Assuming there absolutely had to be a hard fork, what would you like to see added to Bitcoin?

I'd like to see it hardened against rainbow table attacks so Brainwallets are less risky.

Would the easiest way to do this be with a website like bitaddress.org implementing this hardening clientside.

something like   Sha256(bcrypt(Passphrase))
