Cantor once had a functional for publish/load worksheets.
But, as I see, KDE infrastructure for this have been moved to [[ https://kde.store.org | kde.store ]], when Cantor didn't have big developers support, so now this code not work, because kse.store don't have the categories, used by Cantor (`Cantor (Python)`, for example).
After some googling, I haven't found, who are responsed for creating categories, so I create this ticket.
Categories: `Cantor (Maxima),Cantor (Sage),Cantor (KAlgebra),Cantor (Qalculate),Cantor (Python 2),Cantor (Python 3),Cantor (Scilab),Cantor (Octave),Cantor (R),Cantor (Lua), Cantor(Julia)`
