Did this happen? I don't see it in 8.3.

An erase method would be very useful. I find that when I rerun a script that greats a (function graphics) plot it always creates a new window, which steals the focus (and pops up the new window in the wrong place). This drives me crazy. It would be much better if I could erase the old one and reuse the same window. Then my window layout would stay put and focus would stay in the editing window.

Am I missing something?
