Please add support to assign up to 15 keys for spells

Hi,

This has been a long time coming. The UI/UX design for this game has been rather frustrating for years. The more interesting and fun builds require more skill slots but many builds are incredibly cumbersome due to the limitations put in by the UI.

Portal gem for instance is a massive quality of life improvement--why exactly does it need to use up one of 7 skill slots?
Why exactly do auras require using up a slot (I do not want to hear about 'oh you can swap it out once it's on'--that's still incredibly cumbersome and if you die you need to cycle through everything).

The UI/UX limits player's imagination to build characters when it shouldn't and it has not been updated to include more keys when there is now a much greater reason to use many.
