I use LibreOffice 18.104.22.168 in Linux Mint 18.3.
To try “notebookbar” feature I have enabled “Tools->Options->Advanced->Enable experemental features” and restarted office. After that I supposed to find menu “View->Toolbar layout”. But still there is no “Toolbar layout” item.
Do I something wrong or maybe is there another way to enable “like ms office”-interface?
