Add scrollbar to the input text box

[westerntc-gtg]

Describe the need of your request

As a user, when I enter a prompt in the text box, and it gets lengthy, depending on screen resolution, it may scroll, but because there is no scroll bar navigating within it becomes difficult.

Proposed solution

Make the input text box for the prompt scrollable, so that it better fits when docked

Additional context

So I know you can include code by attachment, which helps this some, but if my prompt text is long the same thing happens as in this snapshot:

you can only move up or down by way of the up/down and not by page up page down or scroll wheel on mouse you have to cut what's in the prompt out to get back to scroll up to the previous solutions.
