It would be helpful to see modules come in standard sizes, such as 1" x 1", 2" x 2", etc. This would make it easy to take like-sized modules and use stand-offs to secure them together instead of having a bunch of pieces flopping around. Another item then could be size adapters to make it so that you can stack a 1" x 1" above a 2" x 2".
Ok, that’s my last suggestion for awhile.
