I used it for a long time years ago and it is indeed very great. But its only maintainer stopped around 2021/2022 because he got a new job or something along that line. As far i see he partially returned later but is still looking for more contributors. so the future of the project is not really secure. e.g. see https://github.com/nomacs/nomacs/issues/987

So more eyes on Nomacs would be indeed good.
