Just want to add my concern to the loss of the full TAGS page. I have a deep hierarchy (which will benefit from the ability to display child tags when searching), but when I allocate new tags to a note, they just go to top level. Then once a month or so I have a tidy, and allocate then to the right place in the hierarchy. Currently I have two drop down screens of unallocated tags and no easy way to drag and drop them into their right place in the hierarchy.
