On wide screens the Translation dashboard information can become too stretched:

We can consider limiting the maximum width of the dashboard at a certain point:

The example above applied the following css modifications as an example:

.cx-dashboard {
    max-width: 1500px;
    margin-left: auto;
    margin-right: auto;
}

.cx-dashboard__sidebar {
     max-width: 500px;
}

Further explorations may be needed to determine the exact values to stop expanding the dashboard width.
