This request is similar to Autoconnect ksnip to kde-frameworks-5-core18 and https://trello.com/c/q22ntu0J/245-office20-and-abstractgames-kde5-frameworks-autoconnect.
-1 to auto-connect for the same reasons.
@galgalesh - please see Autoconnect ksnip to kde-frameworks-5-core18 for paths forward. It might be that kde decides to pursue global auto-connection, but if not, there are paths forward for you as well.
