Radio circuits often mention how to create a coil. They forget to mention the resulting Henries.
It would be great if I could enter coil specifics in iCircuit like:

• inner diameter of the coil
• wire diameter (in mm or AWG)
• number of turns
• coil length (spreading of turns)
• coil core (air or ferrite)

...and iCircuit would calculate and display the Henries this coil would result in.
