Change the positioning and size for the pin labels on the shields. The headers tend to obscure them for reading.
Take care of shorting to ground by placing components over the USB connector of the Arduino. FloatShield made this mistake, do not repeat it.
The user reference potentiometer is prohibitively large. New designs or revisions should use a smaller potentiometer.
The images below show the one included in the ArduinoStarter Kit (?):
Compared to the one on the OptoShiled:
The small one has the marking "ACP Spain", the body measures 10mm x 10mm The pins on the runner side are about 6 mm apart. First of all, find a suitable replacement.
This sticky issue and the post summarizes some hardware design practices for the AutomationShield devices. The current list is quite randomly organized, make sure you read it all. Please comment any other ideas that are generically valid.

.3.3V Compatibility
Make the shield 3.3 V compatible at all cost: New shields and updates to old shields (especially those with fast dynamics) should be made 3.3 V compatible. Here are some concepts to consider:
AREF
pin doesn't change anything, device still takes internal reference though. This has been tested on the Zero / Due / Uno without issues.
