Thank you Kai.

I have patched meld/meldwindow.py and meld/ui/notebook.py in 3.20 based
on this commit.

However, I get this error when I run meld:


Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/meld/meldapp.py", line 79, in

TypeError: argument child: Expected Gtk.Widget, but got
meld.filediff.FileDiff


could somebody more experienced with python programing suggest how to
properly apply this patch in meld 3.20 ?

thank you,
