I'm getting ready to run Tyranny of Dragons for the 4th time. and while I love that my players can use this service to track their stuff... I feel that dnd Beyond doesn't really cater to the DM.... I would love to have so many features that should be available that are easy to implement...and should have been the default defacto from the beginning... let me choose the prefix in the encounters for the monster...I can print up base markers for numeric designations a lot easier than I can find alphabetical ones... let me put encounters in folders...and sub-folders... heck... why do I have to enter these encounters by hand....you have all the information in the book you sell on the site... the encounter tracker is just not that good...it's convenient but at this point it doesn't offer me the DM any say or options... what if I want the creatures to roll hit points vs start with just half... 

feel like I have subbed long enough to at least start seeing some functional changes...maybe if I buy some dice they will listen.
