WoW Spell listing by classFollow

Just a suggestion and if it has been addressed in the past then sorry as I didn't seem to see it anywhere. The suggestion I have is when in the WoW section we select the option by class is if we can have a level range inputted as well. I know it isn't much however with so many spells per class out there and soon more, a level idnetifier would make it easy to view rather than scroll through each level.

Thanks for reading..
