<h1 dir="auto">Description of the new feature/enhancement</h1>

<p dir="auto">Hi, I have been using this Terminal for a while and find it impressive. But I have one question/feature request here, I use WSL in my daily work and the new tab is Powershell by default when I open the Terminal or create a new tab(ctrl+shift+t)... Is there a way to set my default tab?</p>
<h1 dir="auto">Proposed technical implementation details (optional)</h1>
<p dir="auto">In settings.json adds default tab entry I think..</p>

What's wrong: I see underscores in the bash console</p>
<p dir="auto">I am not sure what or how this happened, but I see underscores throughout the console window. I tried relaunching, removing my custom settings, changing font, reverting to legacy console and back, but nothing has worked.</p>
