Seriously, 20 years later and you are STILL fixed width with no direct copy/past? WTF?
Are you kidding? I've been doing copy/paste from the Windows command line (cmd.exe) since Windows NT 4.0. (Not to mention setting the width and the scroll back buffer size among many other options.) And all of that is available in PowerShell as well.
If you right-click anywhere in the title bar, you'll get a context menu, and at the bottom of that menu is properties. In there you'll find, on the options tab, a box labeled Edit Options that contains two check boxes: Insert Mode and QuickEdit Mode. These two check boxes are essential for doing copy/paste operations in cmd and PowerShell. Now if you go over to the Layout tab, you'll find you can tweak the height, width, and under "Screen Buffer Size", the "Height" setting there actually the scroll back buffer length. All very handy stuff.
Now once you have everything setup correctly, pasting into the terminal is done by right-clicking in the window and choosing paste. Now copying from the terminal is a little different. Generally, you just highlight what you want to copy with the mouse, then just right-click on top of the selected text. Your highlighting will disappear, but the text was put on your clipboard. If you paste into Notepad (or other app) you should get whatever you copied from the terminal.
