I'm wondering - curious - what "systems" others have devised... I've been playing since March (2013). I've messed around with ways (colored pencils/graph paper/post-it notes) to KEEP TRACK of WHO is WHERE! Who needs feeding/evolving/healing - how to stay balanced for best income - and recently, how to determine who to move where and sadly, who to sell to make room... (I am maxed on habitats, have enabled the Stable to hold 10 dragons but have not started upgrading habitats to hold the 4th dragon). Has anyone come up with a system to keep track of everything?
