Hi!

Agree...

It makes sense to reduce the options to 3-band and 4-band resistors... as the tolerance information is then implicit/redundant/irrelevant. It might be even sufficient to simply mark the 4th band as "optional". :-)

This dialog could be much more nice/useful if we could simply choose the colors of one of these mystic colorful leaded things and the calculator shows the value for us...
Currently, it doesn't really "calculate" anything. ;-)

Additionally, since color codes are pretty old-school and rarely used in modern SMT, we could add tables for 
the newer EIA-96 coding systems.

A quite nice realization is on:
http://www.hobby-hour.com/electronics/smdcalc.php
or
http://www.resistorguide.com/resistor-smd-code/

Try to type in some EIA-96 codes...

Regards,

Clemens
