The user should be allowed to add/delete example projects from the list downloaded. A use case is that Alice creates a bunch of templates specific to the environment at her company; her co-worker Bob should be able to select one (or more) of Alice's templates.
There are various mechanisms for changing the template list:
- Alice publishes an XML file with the list of templates in it; Bob imports that XML file.
- Bob goes to Preferences and modifies a table there.
- Bob opens up the New Template the New Template Wizard, which includes UI for adding Alice's templates.
