This is very well laid out, can't wait for it to be merged so I can add on the serial port support I'm working on for this MLEEDA 10 Port with RS-232 Wired Remote

@ym could you please check this and let me know if you are willing to merge it? I can resolve conflicts for sure but I'm worried that I did not get any feedback on this PR for a last month

This isn’t something we want to support right now. We’re about to implement a feature tracker, and if there’s more demand for this in the future, we can consider it then. Once we settle on a plugin system, this could even be a plugin.

That said, the JetKVM UI generally prioritizes ease of use with optional customization, as seen in the EDID and USB config settings, where we offer common presets alongside customizable options for people who know what they want. If this feature were to be added to the UI, it should follow the same principle.
