I was hoping to have total collection being able to be priced to TCGplayer as well as decklists in general, mixed with having the my collection page easier to read and also showing your total amount you have stored in the collection. I dont mean to say this service is better but I think you should look at dreamborn.ink to see a good way to display collections and lists etc cause it allows you to see what you have on an easier scale.

also for collection I think a filter you should add is to sort by collection number as well since its currently not possible, and if it is it was not easy enough for me to find :)
