Spell Queue

I would like to be able to queue 1 more spell in my spell factory, just like we can do with the barracks. Given the surplus of elixir in the game (especially at the higher levels) I don't see it being an issue for 'hoarding' or 'hiding' elixir from an attacker. It would certainly benefit back to back attacks like we can do with troops.

In addition, can we lose the penalty for cancelling a partially complete or a queued spell? What is the logical / gaming reason to have this penalty? Often I accidentally create a spell - this is either by trying to click the little 'i' and missing, or thinking I am in the barracks when queueing troops and I accidentally create the wrong spell. Or at least give us a 5-10 second penalty-free time to cancel spells created accidentally.
