FEP-c0d0: Context Locking Thanks for sharing that! I did not know that the Lock activity could be applied to children, although it makes sense logically. This FEP only deals with topic/context-level locking, so Lemmy and Piefed's implementation would go further than this. It's definitely worth mentioning within as well. FWIW both Lemmy and Piefed have the concept of contexts, it's just not exposed in the UI. It's pretty trivial to support this FEP with little to no new logic.
