Q&D is pretty minimalist/low volume and mostly plays pretty well with lots of other training. I basically never think about limiting whatever else I'm doing that day or on non-Q&D days. The main accommodation I make for Q&D is that I always do it first in a session.
I've been rotating through Q&D 044 snatch sessions in several permutations, waving the session volume between 60 and 120 total reps.:
32kg x 5/2 (recently transitioned to 6/2)
32kg x 7/2 (recently transitioned to 8/2)
28kg x 12/2 (recently transitioned to 15/2).
Taking a quick look back through my training log, right after Q&D I've done sessions with some combination of 044 power pushups, double front squats, sissy squats, hack squats, ring pullups, ring dips, rows, towel curls, ring fallouts, band pull aparts, clubbell sessions of up to several hundred total reps, calf and tib work, and double outside the legs swings (typically 2x28kg x 10 x 5 sets). Plus miles of Nordic walking. Not necessarily all of those things every time, but usually several of them. I do pay attention to volume in those other drills and keep it low to moderate, although I sometimes go a little crazy with the clubbells. For instance, double FSQ or pullups might be sets of 3, 5, 7, and I'm mostly in the range of 15-30 reps total volume for grind drills.
On non-Q&D training days, I'm doing pretty much the same thing except starting with double C&P instead of Q&D snatches. So I'm rotating between Q&D snatch days and double C&P days, with some combination of the other drills described above after the snatches or C&Ps. Most usually, I'm getting in 2 Q&D snatch days and 2 C&P days, and often 3-6 miles of Nordic Walking on non-lifting days.
I really love the Q&D format because it's so high bang for the buck in terms of time and recovery demand. Even during the school year (I'm a teacher) when I'm overwhelmed and stressed out, I can just do a Q&D session and feel like I'm maintaining a lot of different qualities. And if I have the time and mental energy I can pile on a bunch of other stuff without spreading myself too thin. I also just enjoy the rhythm of the 044 timing, with 2 sets in close succession and then a longer rest.
