Open command prompt

To select between classic command prompt and PowerShell, there is an option in the settings that do not actually mention this particular way of opening the shell:
The only gripe I have with this feature is that it requires you to find an empty spot in the window… which is not all that easy when looking a folder with a lot of files in list or details mode.
But then there is the second way to get to “Open command prompt”: use shift-right-click on a folder to get a new shell located in that folder.
