Add a plugin for the synergy protocol to be able to move Mouse between computers. I prefer to share Mouse between computers but I would also like it if its possible on android.😁 Synergy itself is GPLv2 but the newest software version is prorietary. https://en.wikipedia.org/wiki/Synergy_(software)
Barrier seems to be picking up these days (based on Synergy), it would be great if kdeconnect could be used as a client/server with it: https://github.com/debauchee/barrier
I guess barrier project will want to implement their own app, generic and not specific for kde. See https://github.com/debauchee/barrier/issues/1452
