Maybe HN ruined me, but I'd prefer a UI that isn't very pretty but information-dense, especially for a use case like this, and especially when the alternative is whitespace/tabs-galore in order to make data more spread out.
That said, it is ugly, like most Windows utilities tend to be.
There's still a difference between functional, information-dense design and a missing sense of design or care.
An interface displaying a lot of information, and ways to manipulate data can be functional and information-dense if there's thought put into how to do the layout, usage of colors, icons and other factors (Thinking about power user tools like Logic, Video cutting software, internal company tools or POS software that is used by many, all the time). It might not necessarily look "clean" and beautiful to the uninitiated but it gets the work done effectively.
I'm still of the opinion that hacker-built GUI tools have their own kind of beauty in the way a specialized and intricate woodworking tool might. Nobody shies away from showing some impenetrable command-line doodad with bad ASCII art, why not the equivalent for GUI tools who's audience is the equivalent of your average bash-bro?
