Layers, datasets and projects are organised differently now, and the point of the
rebuild was to make moving through them easy. Drag and drop to move things, put folders
inside folders, and select several items at once to move or delete them together.
More importantly, everything is in one view. Projects, Templates, Datasets, Bundles and
Folders sit together and you filter by type to see only what you want. That makes one
question much easier to answer than it used to be: which data is connected to which
project.
Sharing works across all of it now, not only on projects, and ownership of an item can be
transferred to someone else. Useful when a colleague leaves, or when a project moves from
the person who built it to the team that runs it.
