More markets to copy to would be hugely helpful. Ebay and amazon handmade are the two we use the most but it is such a pain to have to make each new listing when you have 2000+ items!
I have tested Vela out with a free trial. It is useful, but not for the money at this point and with my situation. If eBay listing creation came to Vela, I would probably subscribe. Amazon would be handy, but their system is so complex, that I would not expect that to hit Vela for a really long time, most software seems to stay away from Amazon listing creation.
