Miller is currently coaching with the club's Under-20s but has no intention of stepping away from playing altogether just yet.
It was suggested the 37-year-old could form part of Pedro Caixinha's coaching team at Ibrox although the Portuguese manager has since ruled that scenario out.
Miller is keen to continue to develop as a coach but is not about to hang up his boots.
"My focus is firmly on being a player for as long as I can," he said, as reported by STV. "You're a long time retired so I'm firmly focused on the game at the weekend and continuing my duties as a player until the end of the season, and hopefully beyond.
"When things like that (coaching) are put to you, with more detail and discussions, then who knows."
He added: "I don't feel ready to hang the boots up yet, I still feel like I have a lot to offer on the field at the moment. It would definitely have to involve still being a player.
"I still see myself as a player as much as I'm getting into the latter stages of my career. It will be the next step in my career but I still feel as fit as I did three, four, five, six years ago.
"As long as I'm performing and contributing, which I feel I am at the moment, I still want to be considered a player first."
