I completed my first PCB as a beginner. I will send to factory. Before sending I have some questions (noob question 
).
-I have these warnings. These are not important right ? I now which one has which value so I don’t need to enter a value.
-My second question is POWER pin U$1 VCC connected to N$1 . Why is it saying to me , is it error or something. Second photo for my schmatic for POWER pin U$1 VCC connected to N$1. Everyone says add caps, add caps for IC. I did it but is it correct ?
-My third question is about to LM1117 hole. In PCB manufacturing , I saw LM1117 side a hole. Is it about the cooling right? It won’t be a problem I guess.
-Last question is I have AGND pin but I didn’t use it. I only AGND pin to AGND in schematic.In PCB design I used polygon for GND tp and bottom. I didn’t use AGND for anything on board side (PCB side). It won’t cause any problem right ?
Thank you, again sorry for noob question but I want to be sure before sending manufacturer.
