Have you ever wanted to be able to change the image that gets displayed for the built-in Save, or Refresh command in the screen ribbon, but you didn't want to have to install a shell extension, or a theme extension?

Luminous LightSwitch Types updated today.

This extension now consists of four custom LightSwitch business types:

• a Password type - that hides the characters being typed, as well as validating several optional conditions

• a Link type - that allows you to enter/edit a URL, as well as launch a browser with it

• a Percent type - that stores the value as a decimal, but displays it as a percentage

• an ISBN type - that validates both ISBN-10 & ISBN-13 numbers
