Serial Monitor needs more options

would be nice to have more options

port select and bits/parity/stop/flow options at the bottom next to baud speed, and echo on/off modes

terminal mode (keys sent as they are pressed) or line entry modes (series of keys sent when enter is pressed)

bits/parity/stop/flow options

Why? The Serial Monitor application is designed to talk to ONE device, which uses ONE set of values for these.

port select

In case the OS changes the port number the Arduino is connected to after the sketch is uploaded? How likely is that?

I would like an option that had 'Share' com port, so that my sketches wouldn't refuse to run because the COM port is in use.
