Title is self explanatory - the ability to duplicate rems and portals would be super useful for me although I do have a fairly specific use case.
Use case:
I’m studying a group of muscles which are innervated by the same nerve — muscle name is the concept here and innervation is one of its descriptors.
To test myself strictly and thoroughly, I would not want to find out via the breadcrumbs that X muscle belongs to Group 1 because then I would automatically know its innervation.
Therefore, I moved X muscle under its [more vague] grandparent (named for example, Muscles of the Upper Limb) + kept a portal to X muscle under Group 1 that it actually belongs to — this helps with both easier navigation + avoiding hints in the queue.
How breadcrumbs look before the move:
Muscles of Upper Limb > Group 1 > X muscle > innervation
How breadcrumbs look after the move:
Muscles of Upper Limb > X muscle > innervation
Additionally, I would also like to test myself on which muscles fall under Group 1 but not their innervation (and other descriptors).
This is where duplicating a portal would be useful - I could simply duplicate the portal already present, select all the muscles in this duplicated portal, Cmd + ↑ to hide their descriptors, and make this portal appear on the backside of the group x card.
