FWIW if you listen to Signals and Threads (the Jane Street podcast) they talk about this.

They have dedicated UX designers who do relatively little code but focus entirely on making the UX as optimal for the traders as possible and one of them was on an episode.

They talked about how most of the normal UX rules for SW go out the window because quants and traders have such different needs than "normal software".

Is there any professional software that wouldn't benefit from high information density? Most software design is optimized for the non-users who have to approve it.

		"non-users" are also big targets for software. If you run a software business, chances are you want people who've never used your software to start using your software. In that case, discoverability trumps high information density.
