Just an idea for the layout
I had a recommendation that maybe Riot could add some organization to the layout; not that it isn't organized already I just had an idea. What if players could move around their pages of masteries and runes so when they create a new page, they can choose to move it where ever they want to for organization purposes. So if a rune page or mastery page is created then the player has the option to drag it and move it to other locations and when that happens the page changes to the current spot it is in when the player saves it. For example there are 5 mastery pages created and you move page 4 to page 1, the pages would be 4, 2, 3, 1, and 5 until you click save. Same thing for the Rune pages. This would be an interesting idea to add on to update 6.0.
