I'm mostly thinking of tracebacks which go >10 levels deep, which is
rather common in larger applications. For those tracebacks, the top

now adds another 10 extra lines to jump over :-)
If the slice were instead marked with color tagging, as I hope will be
possible in IDLE and other IDEs, then no extra lines well be needed
That's great for people using IDLE, but for those using the vanilla
Python interpreter, M-A.L makes a good point about increasing the
vertical size of the traceback which will almost always be ignored.
The vanilla interpreter could be updated to recognize when it is running
on a similated 35-year-old terminal that implements ansi-vt100 color
codes rather than a similated 40+-year-old black-and-white teletype-like
terminal.
Making the enhancement available to nonstandard python-coded interfaces
is a separate issue.
Its especially the case for beginners. Its hard enough to get newbies to
read *any* of the traceback. Anything which increases the visual noise
of that is going to make it harder.
