Arduino must have features

Hello,
Features that we all may benifit from:

gauge that displays processing time of each command(ms elapsed to run), debug_step_into feature, debug_step_next, for debugging line-by line. (obviously interrupts would be ommited).

A virtual pins display window (which pins are on/off, pullup_resistor, etc.)
Perhaps expand the Virtual Display Window (components, and modules) and observe the calculations of voltage usage, etc.

I hope you consider adding those features to the next version.
Thanks.
