Set collection improvement
First of all i (almost) like the set collection interface, it's a great idea, but quite missleading and useless as of now.
I suggest a small change that would make a world of a difference and satisfy the whole playerbase (or so i hope).
Right now, i have 2 extension both at 99% (see picks) one is really close to "only" 99% one-of and the other is almost 99% full of 4-of, yet they are showed as the same. One i could consider getting pack, and the other is only missing 2 myhtics.
What i suggest is to add an other yellow chart inside the blue one to keep track of all 4-of. We would then have both the single completion set and the full collection set available at a single glance. fortunatly, those chart can't overlap as you can't have more 4of than 1of.
Hope i've made myself clear and this helps.
