suggestion about alternative input/output layout

In most examples, the REPL loop works in a single window. Each input is immediately
followed by the output of the concerned result. The prompt_toolkit may provide a way
in which the input and the output appear in different buffers. A typical approach may
follow the layout provided in the 'full-screen-layout' example. For instance on the left
pane, one may have the input while the buffer on the right one is updated with the
output of the last result. This may help for the design of board games.

I'm wondering whether it is possible to have a simple prompt loop on one window and the
output occurring in an other.

Thanks.

Start by reviewing the prompt_toolkit full-screen-layout example and the existing REPL loop. Determine whether the requested separate input and output buffers fit the library's current layout model, then define an example or API change that demonstrates the two-pane behavior. The issue does not specify files or acceptance criteria, so the expected result needs clarification first.
