Needs explanation for spreads

The cards are beautiful, and the app works great and offers a lot overall. I only wish it had explanations / overviews for what the different spread types "do" or mean (i.e. Whats the differences between Celtic Cross, Two Choice spread, etc.). Im new to Tarot and would find this info useful (so I dont have to leave the app, google my question, and come back.). Otherwise great.
