This is indenting, which has been mentioned before, and, at the moment, is not realistically possible.
Technically it is possible, but you would have to create a custom window for each channel window, then have the information from the channel sent to the proper custom window, and, for your replies, the information would have to go from the custom window to the correct channel window.
Additionally, if you wanted this same format for PM/Query windows, the same scenario would apply to each of them.
So if you were on 4 networks with 5 channels and 3 pm's each (as an example) you would end up with a total of 24 windows.
