Allow searches of the configuration library to find configurations with particular variables or plot types or descriptions.

When a component configuration is saved, such as of a plot or a plot page, take a png snapshot of the component and store that with the configuration. Then the browser can show the configuration icon to the user as a hint of how the configuration looks. Or the icon can be from some existing set of icons.

The configuration framework may be the place to support redo/undo operations, if a stack of configuration snapshots is kept every time a configurable component is changed. Likewise if the sanpshot is saved to a file, similar to a journal, then the last known good configuration can be restored if a display session should crash.
