I have a few collapsed blocks. I think that from UX viewpoint when I click the bullet of a collapsed block, the detail (zoom in page) should be show expanded but maintaining the collapsed state when I go to the parent (zoom out)
Agree. I can’t think of a case where I zoom into a parent block and don’t want to see its children.
Also, this feature can be very helpful if you have some advance queries with results collapsed by default because they have so many.
I just was in the situation again and want to emphasize my vote with this short comment:
I zoom into a block to focus on the details (and blend out the surrounding) and see nothing but the top parent block text. I agree with @Cobblepot - I can’t think of a situation where this would be useful.
So at the moment we have to manually expand the block. This seems simply like an unnecessary inconvenient step.
