I’ve been using input-remapper with my Naga for a long time, so it should work (Tumbleweed with Wayland). But the software is quite quirky and can be a bit of a pain to setup and learn. Hope you manage to figure it out!

In Dolpin settings, under Interface > Previews, there’s an option for previews from remote storage. Not sure if it applies to connected devices or just network drives though.
