For input, suggest to add one more 0.1uf, 1pcs each for pin2 and pin11
For Feed forward, 1.8V can be NC first, and 3.3V/5V, suggest 0+100pf as default, and based on transient performance to determine fine-tune or not.
Considering the derating of output caps, for 5Vout, suggest to reserve 1~2 pcs more 47uf, NC for backup
Others looks ok.
