Most important changes from v1.2:
Dual device mode with built-in supprort for measuring input lag
PNG export features: non-transparent, not only 800×600
Automatic saving of several settings
Hotkey for collecting
Sum vs. Time plot type, just like in MouseComparator
Frequency vs. Time plot type
Concerning counts vs time graph: what does the y-axis display?
I can see a dot every 1ms (1000 Hz mouse) which is good. The graph looks like a hyperbola. What does this mean, there is no unit on the axis. What exactly goes up and down. The amount of counts stay the same, namely 1 count every ms.
