Potential for improvement not yet used

Have called in the past year the service my wishes, complaints. It has promised to change, but unfortunately?
For me, the X7R is of little use.
Reason: The camera can be operated via battery or power supply. If battery is empty, so you can install a fully charged spare battery. On external power, the knock-out criterion is the memory card. The can be replaced quickly.
What makes our remote control? Battery must first be charged before re-use is possible. No external power is possible.
Other weak points have already been mentioned
