Faster confirmations is the only thing I could possibly wish Bitcoin to have at this point.
agree about that, faster confirmations should be a must, if we want that more people use out bitcoin, it must be done soon, lets hope with the "next changes" the time between confirmations are lower.
I could not think of any, but it is very evident what is lacking in the bitcoin economy: merchants willing to get paid with bitcoin on their merchandise. The concepts of bitcoin is almost flawless, though there are some factors that we need to reconsider if we are preparing for mass adoption (ehem, block size).
thats another important point, merchants, btw since the adoption of bitcoin is something scalable, my wish is that this happen with merchants too.
