Hugely frustrating that when selecting multiple entities in the entity viewer you can choose to hide them but not unhide them - you have to do them individually!
You can disable or enable multiple at a time but it does not affect the ‘hidden’ status at all.
I’m building an auto-generating dashboard that requires entities to not be hidden and be assigned to an area - I hid a load of stuff by accident and now have to pick through one at a time unhiding them - very annoying!
