Trying to get an answer to the question How many sub-levels can there be in Dolphin actions/services? - I want to know if the line that starts with X-KDE-Priority= in a service file (in ~/.local/share/kservices5/) that helps control the order of items can get a different option than TopLevel.
KDE service files: can `X-KDE-Priority=` be used with othe value than `TopLevel`?
