Feature request: additional projection variables (Dohoung Kim)

[jamesjun]

Adding additional projection variables: In ‘Time vs. Amplitude’ window, the command ‘Shift + Left/Right’ is for showing different features, but for me it actually changes sites in 4 steps. Also, for the further manual separation, I thought that adding projection variables related to the waveform pattern might be helpful (ex. Peak (Vmin) – valley (Vmax) spike width, energy, rising and falling slope). -Dohoung Kim
