Review Comment:
There is also a second way to start the TUI:
1) `ballista-cli` - to start the CLI
2) in the CLI execute the `\tui` command

+
+### TUI Features
+
+The TUI provides the following views:
+
+- **Executors**: Lists all registered executors with their host, port, CPU
cores, memory, and current job count. Supports sorting by any column.
+- **Jobs**: Displays active and completed jobs with their status, start time,
and duration. Supports sorting, job search (`/`), and shows job details on
selection.
+- **Job Stages**: When viewing a job, press `Enter` to see its execution
stages with input/output rows, elapsed compute, and task percentiles.
+- **Stage Tasks & Plan**: Within the Job Stages view, press `t` to see
individual task details or `p` to view the stage execution plan.

Review Comment:

```
I know that the context-aware keybindings in the footer say "Close popup"
but here we have more room, so we can use `Return to Job Stages popup`, since
it is more correct.
