  How do you pass in/access google gadget user preferences?

  Most of the interesting google gadgets require user configuration.
  For instance adding a bunch of world clocks for different timezones http://www.google.com/ig/directory?url=www.ljmsite.com%2Fgoogle%2Fgadgets%2Fworldclocks.xml

• From Michael Roff:

  I agree .... without the ability to edit the custom inputs of a google gadget, this feature is worthless, which is a real shame as it provides so much potentially great information to add to customised dashboards and alike.

  It would be nice to hear back from Atlassian if this is something on the roadmap or even if it's within the control to provide this feature.
