I was writing something longer but essentially it comes down to this: Whether or not this serves the canonical use-case is mostly a topic to debate, when it comes to a general sentiment of “should something happen”. If there is someone doing the work, then the question left to ask are: Is it in line with the purpose of Syncthing and is it maintainable? I don’t yet see anything speaking against the former and the latter is to be determined in review. Details like whether the distinction should be hidden for small numbers of devices are definitely up for discussion. To me that also seems pretty unproblematic, as it just uses a bit of vertical screen estate, while horizontal space is the one that’s usually missing.
