Honestly, I'm getting really interested in what you find so offensive in ISE. I mean, I can see it being not so great, but being straight out offensive I can't really understand. It is perfectly understandable if you don't like PowerShell (it is kinda weird). But ISE? The most different thing in it is a "fancy" tab-completion, and that hardly can be reason to so deep hatred.

And I'm not saying ISE is the best thing ever or anything, but it is a significant step up from conhost, and honestly not really lot worse than xterm in many ways.
