Where are good examples of web applications designed for expert and heavy use?

Question

I spent most of my career on a career, or external applications for use as daily business tools, at least for semi-skilled employees, for example. order tracking, sales capture, etc. The fact that I helped build well-formulated tasks is quite comfortable, but I'm still looking for excellence in creating such applications, as well as a fashionable emphasis on a more personal relationship with the user interface.

Can anyone recommend reading this kind of application (LOB?) Online today? Any available examples to study?

Answer 1

I suggest you read. Don't make me think . Do not think that interacting with user interfaces is inefficient. I suggest the opposite.

In fact, this answer contains many useful links.
