Without too much change, what I'd LOVE for Sonoff A
1. Ability (with a jumper) to connect / disconnect the relay to Mains
--> would be able to toggle a 24V power supply
A 2 state relay might be a plus for some applications
2. 4 Pins (GND, 3.3 volts, Rx Tx) already soldered for easy heack / Firmware upgrade
3. A connector for GPIO input
4. Din Rail mount
