I adore my Sable but I wanted it to have two qualities from other guitars: the built in the tuner from my Martin and the pinless bridge from my Breedlove.
I spent a long time trying to design and 3D print an under-bridge gizmo to solve the second problem and realized (and I can't believe it took me this long to figure out) I could just put the pins in from underneath, thanks to the beautiful McPherson side hole. Preserves whatever sound quality the engineers had in mind with those tinkly glass-like pins and gives me that palm contact I want with the saddle for more control of subtle palm mutes.
The tuner also took advantage of the side hole. I took a cutoff wheel to the clip of my $50 PolyTune till it was a flat surface, then stuck it to the inside of the guitar with double-sided gorilla tape. So far it's perfect. No buzzes etc.

The reason I like pinless bridges. I swear it gives you more tonal control of mutes:
