There should be a solution dealing with Top-level Concepts.

Tagged which can be opened by keyboard-driven workflow.
I think stub can’t be the ultimate solution to deal with top-level rem. Many other useless, auxiliary rems are also stub. This would be messy as KB growing so they should be distinguished for better UX.
