Nope. It's shell based by default. You can open it also as a QT app, like IDLE, but by default `jupyter console` is via terminal.

Indeed I'm against too, and I wrote it. And if you read my proposals, I do not suggest any magic word

I know this, but it should be the default behaviour, IMHO. I mean, you can invoke `help()` in REPL but also in a `.py`. It makes no sense, but you can do it and you have not to import a separate module before.

This is fixed by many terminal editors, like `vi`, with bracketed paste mode, as I wrote.

A workaround could be simulate input by user. Ugly but effective.

This could be IMHO delayed, or not implemented at all. If you don't like the colors, you can always not use it :D It will suffice that the colors will be as much as possible readable also by the majority of color-blind person.
