I would like to be able to load local widgets with a little more control.  From what I understand, the profile.xml is loaded when a channel is loaded, however I'd like to have the ability to load widgets conditionally depending on the channel.  For example, if I switch to a channel called "clocks", my development/test/sandbox widgets from a channel named "test" aren't loaded?

Is there any way to have the profile.xml only add widgets depending on the channel being loaded?  I don't want to have to pull the USB stick to control this and wasn't sure if there was some other way.
