You start the feature request by "That way I could easily determine where I've used variables or functions or Presstalk commands...", but what is your actual request? What does this refers to? Can you give us more details?

For the "bug report", this isn't a bug. Object positions in a group are relative to that group's position, so if you remove the group, it makes sense that it would reset the object's position to a default value, since if it used the old relative position, it could potentially bring objects outside the page, since the position is now absolute outside of a group.
