If easyeda pro could check DRC using exactly the requirements that JLC use, this would hugely improve the user experience and benefit easyeda group immensely.  For example, you could select in a menu that this is a 2 layer, flex pcb, and easyeda check to see that it passes JLC capabilities.

Benefits:

1. JLC has less errors in board orders - thus saving JLC time and money checking and less contacting customers.
2. User does not waste time emailing back and forth with JLC support.
3. User gets board orders faster.

This would hugely improve the order process.  @dylan
