After playing a bit more, I've realized part of the problem is that it's subtle when a client has the relevant physical feature. Some futa have endowments that just look like puffy mons at first glance. Or you have to scrutinize the latex to determine "Is that a bulge or not?" The boob sizes are also fairly subtle, and with only 2 or 3 clients on screen at a time, it's not trivial to quickly compare and be certain that they're actually "big".
Increased font sizes on the customer requests would also be nice.
