I have made by your requests:
+ "Esc menu" increased
+ Info about hot keys in the "Esc menu"
+ Possibility to record videos "F1" start, "F2" stop
+ Possibility to make photos "P"
+ Additional cameras rendering is a huge FPS killer. Because of it, by default monitor for Photo camera is off. You can make photos without monitor. But if you have top hardware, you can turn it on.
