1st issue: Add icons to the panel, use icons only Manager. use non KDE packages as well (Like: Firefox, Libreoffice, Clementine) Change the order of the icons with drag & drop. The order changes. Now open the programs, the icons order will be restored to the original. 2nd issue: right click Pin cannot be used on wayland, it is greyed out.
