Minor issue occurring in the outline view. When hovering over an element, the delete icon is the last one on the right, even when there are custom attributes or other indicated properties present, as shown in the first clip:
However, if you are clicking again and again in the same space to delete multiple elements, when it comes to the one with the custom attributes indicator, it first pops the delete icon to the left of it, then after a single click on the element, the custom attributes indicator disappears and you can now delete the element.
This is a very minor thing, but might be one to nip and tuck away
