The Windows Terminal’s Always on Top functionality makes it stay on top of other open windows.
Here’s how to enable it in Windows 10:
Press the down arrow at the top of the Windows Terminal window.
Now, hit Settings.
Hit Appearance in the left sidebar.
There is a toggle beneath Always on top on the right pane.
Turn it on (to enable) or off (to disable), whichever you prefer.
Click on the Save button.
Remember that this feature will remain enabled until it is disabled.
