Even better, instance level tokens, so that they be also visible from the design studio. Useful when creating emails and landing pages in the design studio.
This is an awesome idea. There is a definite need to create root folder (or instance) level tokens for things like copyright years, addresses, logos, and other company wide info that has the potential to change.
This has become reality today (?). Now my.tokens can be defined in the admin area where they are valid instance-wide. They can also be set (or overridden) on Workspace level. I think that's a tremendous improvement!
