Will there be the ability to generate encounters through D&D Beyond? As you know, encounter math is challenging and web based tools are very useful in doing the math for you. The stat blocks are amazing, and the easy of use to filter and find the monsters is great, coupled with an encounter generator and this would be exceptional. 

With any luck that will be part of the "Campaign Management" of Phase 3.

 Encounter generator and calculator would be amazing!

Looking at what 4e DDI tool had that would be something that would belong in the Phase 3 Campaign manager, keep giving feedback about phase 1 and make sure to check out the information on future phases :)!

I was thinking a encounter generator, simple random dungeon map, and random adventure hook generator 

Fingers crossed this is in phase 3. Initiative tracker and encounter generator (both auto and manual) would be amazing

For the DM having a CR calculator would be great, perhaps linked to a list of monsters (I know it is only one extra click but...)

I've found a good one here: World and Encounter Generator 

map / worlds, dungeons, etc. third party so i hope i don't get anyone in trouble. but yes, an official one would be great. 

Also think Google Maps for the Forgotten Realms would be an awesome addition.

Google Maps for any popular past worlds would be AMAZING.  I'm hoping for a Google Maps for Krynn personally.  It's where I came up as a PC and DM.
