I love kicad and use it daily.

One of my most wanted feature would me to be able to select a trace and get simulated electrical characteristics, like resistance, capacitance, inductance (for example to design a loop antenna, I integrated a few of them in my lastest PCB, for NFC, and had to calculate by hand)...

Of course this is not a small feature but wishing for that says a bit on how good kicad has become, there is very little small feature to wish for as most are here.
