> Bloomberg Terminal Is Ugly and Clunky

What, not enough white space, animations, and shitty, obscure menus for you? Or maybe they need Material 69 or Liquid Glass?

The target market is "power users" who want maximum functionality and don't care much about prettiness.

I used to work on some of the code behind those "clunky" screens. I would say that Bloomberg UIs generally do quite a good job of making the functionality scale - you can do basic stuff quickly with sensible defaults, but when you need more sophistication the UI lets you dig deeper, and deeper, and deeper.
