BIG MISSES : Key features: Diagram is missing important visual information such as cardinality and keys

[bencodesall]

Diagram should have global and/or table-level "show indexes/keys" option that adds section below each table with names of keys and indicators for (PK, FK, IDX, etc.) ... this is a huge miss.

There should also be cardinality indicators (i.e. crows-feet or otherwise) on the connection points to fields and relationship lines ... another glaring miss.

Animations showing the direction of the relationship are not very helpful, especially when the relationship line is visually very long, which can happen really easily in big tables. Either make the whole line animate and not a single slow "droplet" going down the line, or put some kind of arrow representation on the line. I like the former as the arrow representation could become cumbersome and missed on spread out tables with relationships.

Auto-layout feature seems to be missing.

While there's lots of "other" niceties in a ER Diagramming "thing" these ones are probably some of the most important and represent things that might hold many users back from using the tool. I would personally require any diagramming tool I use to have them. Hope the team can get that on there, since performance looks pretty good and the native feel is a nice touch.
