This option may seem easy for the user, who can make changes directly in the GUI. But it was already available before, via the .signalk/baseDeltas.json file on the server. Personally, I prefer options distributed by the server and available to all users, but I've noticed that this isn't necessarily the opinion of the community. So why not have 2 options, local and remote.

The help file should be updated to explain how to use this option (same for Decimals option). https://github.com/SignalK/instrumentpanel/blob/master/lib/help/help.md?plain=1#L345 How to activate it, how to reset it, the difference between local and remote overload on the server.

It's true that I didn't explicitly refer to the displayName key in the online help: https://github.com/SignalK/instrumentpanel/blob/master/lib/help/help.md?plain=1#L380 but rather in the general FAQ: https://github.com/SignalK/signalk-server/wiki/FAQ:-Frequently-Asked-Questions#how-to-add-missing-units-and-static-data-eg-displayname

When there is an overload with the displayName in baseDeltas.json, the user doesn't know if it's a local overload or coming from the server.

The Label is not available in Analog mode.

Sigh, metadata editing is in pretty sad state, could use a bit of developer love.

I'll agree that the proper solution is probably a better way to edit metadata. However, in the meantime for many users I think a local label implementation like this would be stellar.

Metadata editing will probably be published soon https://github.com/SignalK/signalk-server/pull/1730
