This Needs More Attention People! - Mastery Pages

Only because I feel like it could be easy to do, but I don't know, I'm no programmer. If only you could rearrange your mastery pages by just clicking and dragging that page next to the page you want. It would really just make cycling through your masteries a lot easier. Say you wanted an AD Op Thunderlord page as well as a AP Op Thunderlord page without having to last minute edit that page before a game starts that you may or may not forget to change back for the next game. At this point, you have to make a separate page which is fine, however, maybe you don't realize you want this variant page until after you made 10 other pages since your original Op Thunderlord page. Now, if you're somewhat organized, you would want your pages in some kind of order that will be easier to find, so, you have to add a page, make it like the previous page, then go to the page you mimicked, mimic the page before it, and so on until you get to the page just before your original Op Thunderlord, then make the variant you want. Sure, you could just remake the original at the bottom of the list and after, make your variant, but now it's just in a different order. You say,"Oh, that's why there is fair time after champion lock-in to hunt down your list of runes and masteries". Listen, sometimes last second decisions are made in norms, ranked, 3v3, whatever, but if you've played as much ARAM as I have, you should know there's always a last second trade or reroll to trade that you might not have time to think about the difference of AD Op Thunderlord and AD Autos(you might want AP Autos for some silly reason). You see AD, you select, game goes to loading screen, and you realize it's AD Autos and not AD Op Thunderlord.
