Problem Statement

Text becomes more of a wall of text in the cli, it is so hard to scroll and make out where are user prompts in the history of cli output, where the thinking part, where the communication to the user.

Lately you even removed thinking from being darker text to the same color that output to the user uses. Now it is hard to distinguish between these.

Even codex looks more legible when you scroll. Claude code, on the other hand, becomes worse at this.

Proposed Solution

One way, font color variations. Example, like you had for thinking a darker font color a number of version before.

Second, add horizontal lines.

Third, better one. Wrap text in colored border. Green for, say, user prompts, blue for thinking, orange for communication with a user. Maybe you don't have to make a box, maybe even just left border coloring only?

Alternative Solutions

Use color for font?

Maybe use bold, italic, normal text differences?

Use Case Example

I want to see user prompts to be easy to be found, so you can say, yes, everything below belongs to that prompt. Now it is just a wall of text, you have to read words..
