What feature do you want to see added?

The Animal Crossing: Happy Home Designer's additional methods in the Data Store protocol.

Why do you want to have this feature?

Happy Home Designer's online services appear to be very similar to Super Mario Maker's, even for a gameplay style. I have a feeling that it was a test to see if online data sharing could be done on a 3DS, and then the same server and codebase was used in the Super Mario Maker port to the 3DS. The UI even looks the same - and so are the method names in the extended Data Store protocol.

Any other details to share? (OPTIONAL)
