Thanks for the patch. Adding the feature is somehow easier than I expected. After moving the sample text to module level, which I considered doing before, saving edits for the duration of an IDLE session turned out to also be easy. 
With 11 point Lucida Console, there is room for 5 more lines, without erasing anything, before anything scrolls off the top.
I expect that saving changes across IDLE sessions would be much harder and likely not worth the effort. I think that exploring font choices is likely rare enough that there is little need to do so.
