Making it so that you can custom make monsters would be a LOT of work although nice, and would love to see it in the future. What I would like to see sooner though is minor things like being able to change the hit points (like maximize for battles). Adding monsters on the fly during a battle without having to back out and edit the battle. And when you add a condition, have countdown timer of how long the condition is suppose to last instead of it just keeping track of how long the condition has been up.
Have purchased all of your apps and will continue to. Keep up the good work!
