New Post: returning player, need help adv editing

returning player here, haven't played D3RoS since early 2015 (jan-feb), and haven't used the editor since that time too, just bought an activation key code for the new editor and awesome job CKY and crew creating this editor, i still got the basic knowledge for basic editing, just need a few pointers on advance editing and a few questions...

on Item > Properties, what is the Rank for again?
also for Weapons and Armors what Tier Quality should i go for?

as editing for Ancient items on Properties > Flags, which one should i pick? as there are 5 Ancient and Ancient Enchantable to choose from?

i know back in xpgamesaves i figured out by my own how to put a 7th affix on an item, can anyone refresh me up how to do this again?

also lets said on a weapon item that have already 6/7 affix without the socket affix, and in-game i tried to use the Ramaldni's Gift to give it a socket, will it work? or did anyone tried this yet?

how do u create or add affix on a Gem or Legendary Gem?

lastly does any of this modded item works if i transfer/export it to PS3>PS4? cuz i heard from an old news from Blizzard ago that any gear/equipment with more than 6 suffix will not work in-game

thanks in advance!
