Requirement --> Merge Catalogue, Categories and Product level(-s) 

Driving reason --> Define a brand across category: Moschino, Jeans, shirt, boots

Issues to solve:

• Search all products (don't need to click on categories anymore, before I can search)
• our click paths are way too long: Select the connector 2. Select the connection 3. Select a category

Dev notes (from JanS): Eventually we can add a flag per component so pre select connector and connection so an editor must not mess with it on every content change
