Hi @Chris , sorry I’m not sure what you’re referring to, but we haven’t changed the menus recently. Do you have a pointer or screenshot of where the issue is? Removing a stack should be either Delete to delete the stack and everything inside of it, or Ungroup to remove just the stack but keep the things inside of it around. Both are available in the right click context menu if that’s what you’re referring to.
Re: columns: a “columns” always needs to sit tightly together with “column” children. So it doesn’t make sense to ungroup either a “columns” nor a “column.” If you want to move the contents out, you can drag the contents out, and then delete the columns + column.
