How much ongoing development is needed for something like this? I've been using synergy/barrier for years and the features I need have changed barely if at all during that time. Seems like a prime candidate for "finished" software.
Synergy doesn't work on Wayland, so I can't use it on Fedora anymore (unless I switch it back to X).
There's always new feature requests. Drag and Drop files is a common one. I personally think that's scope creep, but I can see the appeal. Synergy and barrier already establish an encrypted connection between machines, so copying a file seems a good fit. At very least a "Synergy send to ${computer}" share/send to option would make sense.
Here's Synergy's roadmap, and since Synergy and Barrier are the commercial/open-source fork of the same ancestor, Barrier probably has received similiar requests over time.
