Adding Iyyun to your B'qi'ut

Let's say you're learning Masechet Shabbat b'qi'ut in order to make a siyyum. What can you add to spice it up with some Iyyun?

The simplest approach is to learn 1 or more sugyot there b'iyyun.
But I'd prefer to think outside the box and give some non-simple answers! :-)

1. Learn Hilchot Shabbat. This would add a dimension to one's b'qi'ut learning. That learning itself can also be at various levels.
2. Learn the G'mara b'qi'ut, but learn the Mishnayot b'iyyun. EG take the "Yachin uVoaz" edition and learn the various commentaries. Add Rambam, Kehatti, and Artscroll's Yad Avraham.

Shalom,
