There would be no missing .ini files. They would be there from the start. We have 3 of them now (engines.ini, favorites.ini, and retro.ini for Modern, Special & Historical, and Retro, respectively). We just need to create a new one (e.g., special.ini) which will become the list of Special & Historical, currently held in favorites.ini, freeing it up so it can hold just your favorite engines. You would then also have a Favorites submenu where you can quickly access this shorter list rather than scrolling through all the engines. Obviously this would benefit the DGTPi and Rev II the most. And it would be optional - you don't
need to use it. I would suggest populating it with the latest Stockfish version as default (copied from engines.ini).
This is a low priority enhancement. Just something for the future...
