A way to make the Runes and Mastery pages 10x better.

Ok, So i know what you were thinking, I'm talking about the runes and masteries themselves. False. Lets talk about the order your Runes and masteries are in. I'm talking about the first Mastery page you made. How it is forever stuck at that Number 1 Spot. But lets say you have 20 Mastery pages, and you want to group them by role. Say 4 for each role(top mid Jung supp ad)But you created them at different times. And all you want to do, is Drag that particular mastery page, and place it in a different order.So the Jist of what I'm saying is, You want to group master page 14 next to Mastery Page 4. But in order to do that you need to either delete mastery page 4 and 14 to make 19 and 20 next to each other, or just deal with them being out of the order you want. I always thought this would be such a nice tool to have, Just to be able to click and drag the rune page/ mastery page tab to put them in the order you want. But hey, maybe you can do that and I just don't know how. Hope Riot see this.
