"Shares" folder

I just wander if somebody can help me with this. After upgrade to Nextcloud 15, all newly shared folder appear in “Shares” instead on root folder. This cause me some issues as some folders related to each other are in different location.
Could you explain me how this works and how can I mange it please?

  1. Can I disable this feature? If so what will happen with existing folders which are in Shares?
  2. Can I decide where newly created folder is placed?
  3. Can I easily move folders between Shares and root? If so, could you tell me how please?
    Best Regards

Can somebody help me with this? Can I just move the folder from “Shares” to root without any issue or not?
