KDE Connect already allows to connect a Plasma PC to another one (or a Plasma Mobile device to a Plasma PC). Based on that, it would be awesome if KDE Connect could share common settings and data of the two Plasma Installations For example: - Passwords stored in KWallet (enables KWallet to be a shared PW manager). - Settings made in Systemsettings like hotkeys, colorscheme, nightcolor, general look and feel, regional settings). - Settings made in KDE applications like Dolphin (taskbar layout, remote folders), Okular (taskbar layout, display settings), Kontact (mail-accounts, mailfilter, notifications settings). This could be on an explicit base (the user has to initiate syncing and its done just once) or automatically (every time, when a change is made). I would expect a significant simplification of setting up a new PC if you already have another one and taking care of multiple installations. From the technical point of view, I would say a protocol/API makes sense, that applications can use to share settings, so they somehow report what settings are sharable to KDE connect which shows that in the GUI.
