lol. There is a niche for it for people like me who don't want to pull in all the baggage of a fullblown desktop environment. Like, I'm sure lxqt-ssh-askpass (which I considered using because it's in my package manager) *looks* prettier, but I don't want to install the rest of lxqt just to get it.

Thanks for the tip, that's useful to know.
