Would love for there to be an export/import tool that could be used for environment setup and test data. The concept of this is that you could export the basic structure of your production server (not patrons or items, but css, jquery, reports, rules, preferences, etc), and import it quickly into a sandbox so you could test your setup against the master. Then, if you created sample items and patrons, export your setup and test data from the sandbox. That way you could reuse these setups against a sandbox easily without having to start from scratch.
