1. The download of blockchain is displayed in statusbar. It's either progressimeter or percent counted.
2. Current bandwidth utilization
3. New Advanced menu with items such as "Manually Add Peer..." and "Rescan Blockchain" and other command-line only switches.
I tried to imagine and visualize how to improve the Qt version. But I figured out that it's like trying to make elephant fly like a colibri bird. It will never happen, the Qt version UI is so unergonomic and the Qt is not meant with MS windows UI in mind. So I see no way to make the current Bitcoin version as usable as it was in 0.4.0
1 and 2 are good ideas, but i think a graphical solution is still better. or both with a switch in the options menu. for most users, the numbers are just a little bit too much information. they just want to know if the connection is good and the blockchain is up to date. or not. rescan blockchain should also be in the avaible somewhere, alongside an explanation when it might help.
yeah well, whats the alternative? sticking to wxwidgets gui obviously nobody wants to maintain doesnt seem like a good plan either.
