Thanks for the wonderful plug-in designandsuch! It really makes the tedious process of converting to and from a snap.
If I could submit one small request - when converting a unit to feet, it would be quite helpful to be able to view the results in feet and inches. For example instead of "Units 222cm Feet > 7.28346... Feet" the output of "Units 222cm Feet > 7 Feet 3.4 Inches" would be be quite a bit more useful for most casual unit conversions.
