I have been following this for a while now, but just now coming to write up some thoughts.

First - great start. I love the way this looks and feels and am very excited about the concept and platform. This could be big for players!

I like the look and feel of the entries - the artwork, text - but particularly love the colored links with the hover-over ability. That makes getting definitions easy or getting more information when making choices.

Some ideas / wishlist:

• Make artwork available to reference by DMs from creatures to NPCs (a bank of them) to locations.
• I have always found some rules hard to find - like passive perception (please add a hover definition for that). Also, anything on a character sheet should have a quick-reference area to get the definition
• You will be adding a general search eventually, but I would love to also see one that is build more like an FAQ for rules. Like typing "Can I use a spell to attack as an opportunity attack?" This would short-cut in combat questions or allow players to pre-search their next move.
• In future releases - can you also drop this into or drop a service into to run an online game all in one platform?
• What about a connection place to meet for on-line games - like "The Tavern - where adventures begin" or "The Yawning Portal"?

Question - in the paid version, will non-SRD info just be expanded into the existing entry? Like the extra monastic traditions under that heading for the monk?
