Ok, this is much much better than what I have :) But I really don't need so much functionalities. moreover, as I said, creating a shell is not so much of a problem. Bigger issue is to have a shell where you can write commands in the left side of your terminal and se a real-time output in the right side. I just thought there is some wrapper or screen emulator or something like that.
Thank you :)
Corion's solution is quite nice, but I worry about safety of such an approach. Open solutions an pipelines ar eusually safety hazards (This is my personal opinion!!!)
