Tested and it’s beautiful!
Thanks to the hints appearing when running the new evernote for ios you’ll learn that you need to swipe an existing tag to the left in order to make the menu button appear where you can, among other things, move your tag in the hierarchy.
I find it a step too much but it makes room for the arrow indicating you can expand/collapse the nested tags.
Well done! I just wonder what king a visual would have been a better indication to remind you that you can swipe to the left while you currently have none. You must know and remember that.
I am so glad I can browse and manage my tag hierarchy on my ios devices ! Thanks!
