Pets is one of the best design part of Adom, ton of good details, many points much better done than in most games. Sadly it is underused just because of few design flaw, speed management is one of those flaws. Nezur idea seems good, i like it's simplicity, unlike slider variation manually controlled. But I have to admit that for a veteran and if pets are really useful then idea based on sliders would be better.
My experience is that it's good that you run a little faster than your pets, there's many advantages to this. That's where sliders could be better. Also it's not good if each time you start a fight you need think to deactivate the option. It's like any auto pickup idea and like in many games, the best would be a different behavior when a fight is threatening or is starting than when there's no clouds around. I mean a feature that auto disable once you see a non tame monster, and enable (if activated) once you don't see any non tame monster.
One important point is that 'w' commands works with pets, it's probably an important cause that nobody use pets.
No vote, enough people vote yes anyway and I feel something more sophisticated should be better but I don't have any clear suggestion.
