You can make Windows Terminal open in the center of the screen & not on the top left corner via its Settings or using a Settings.json file.

Customize Windows Terminal with themes, fonts, and background images to boost productivity and give it a modern, personalized look tailored to your workflow.

With the Terminal, Windows has a common interface for Powershell, Command Prompt, and Azure Cloud Shell. This allows you to start the terminal directly with the command prompt.
