Within the data download interface in HUB, there are several filtering options along the left hand panel.
It would be great to be able to disable one or more of these filter types when they are irrelevant or blank.
If you are only hosting a few datasets and they are all 'feature layers' - the 'Content Type' filters on the left still displays with all different types of maps and app options that are not even available. This confuses the user and should at least be blank if these content types are not available in the download list.
