All Lightning Components not appearing in Sandbox with Custom Domain Name

It is a bit of a bummer but honestly there’s not much in ui: or force: that’s all that useful — most of the stuff there that is useful could be recreated in custom components very quickly. A lot of the components are far too generic or low-level to deliver substantial value.

I also have been told that over the next year, some of the “more useful” ui: and force: components will be made global again, and that they’ll have DESIGN files added to them to make them more easy to use, which would be great to see.
