Question / Suggestion about runes and the way they are purchased.

So right now, when i create a rune page i can pick the runes i own from the menu on the left and place them on my rune page. If i want a rune i do not own, i have to go away from the runepage, go to store, to gameplay, to runes, find the rune, purchase it, then go back to collection, runes and then can add to the runepage. WHY?

Wouldn't it be way nicer if i could see all runes in the left menu, owned or not and buy one directly there to then place it on the runpage? Why do i have to hop around so much?

I mean, i understand that its not really a needed change, but it would be so much cleaner and easier that way, dont you agree, @Riot?

and talking about rune pages, WHERE ARE THEY? can we not buy additional ones anymore?
