bpo-27755: IDLE: Convert configdialog DynOptionMenu to ttk OptionMenu by csabella · Pull Request #3215 · python/cpython

I know you may want to get rid of Option Menus, but I wanted to show you the ttk version. This was too much of a change to include with the first patch.

This is a definite improvement. A single OptionMenu could work for a unified list of keysets. For themes, I am thinking of a listbox, as with fonts, so one can move around to see the effect of different choices without having the box close.

Why? The change is still needed.

Right. I found where I rejected this in its current form, and added more on current uses and replacements.
