++ (doogie)DynamicViewEntity(dve)
+  + (doogie)support for anonymous-views
+    this requires being able to add 'ModelEntity' to ModelViewEntity, instead of just entityName.
+  + (doogie)distinct, orderBy, condition
+    this is just exposing ModelViewEntity.ViewEntityCondition
++ (doogie)QueryBuilder
+  ListQuery query = delegator.query(entityName).useCache(true).distinct(true).byAnd([:]).byCondition().byRelation(relationName).orderBy([]);
+  query = query.subList(i, i);
+  for (GenericValue value: query) {
+    // ListQuery implements List<GenericValue>, and doesn't query the database at all until
+    // it needs real values.  At any pointed, you can continue to refilter the query, and
+    // it will throw away the result values, so that the query will run again.
+
+    // the pattern used for this is a read-only List, and each manipulator method returns
+    // a new copy of the ListQuery object.
+
+    // This use-pattern is similiar to perl's DBIx::Class.  I have a tool that was
+    // implemented first in perl, but with an ofbiz compatible database, that I then
+    // reimplemented in ofbiz entity calls, to get more speed(and better transaction
+    // handling).

+* (doogie)Modify sql code to do something similiar to the above.

++ (doogie)OFBIZ-3959 - Introduce a ModelEntityReaderBuilder to decouple ModelEntity and ModelReader
+  I have this already started in another branch, I need to bring it here.
++ (doogie)Combine delegator name fields into a DelegatorName class.
+  I have this already started in another branch, I need to bring it here.
++ (doogie)OFBIZ-836 - Bug in SqlJdbcUtil.java regarding outer join in oracle theta join mode
+  We have a client that wanted us to use oracle, and I believe this one might be fixed now(in trunk).
++ (doogie)OFBIZ-1232 - Data filtering in entity views
+  I am guessing that this is already done, just might need to close the issue.
++ (doogie)OFBIZ-3520 - revision 897605 breaks certain delegator.find() EntityListIterator calls
+  This was fixed long ago by David, but the issue never closed.  I actually have a test case in another branch.
+* (doogie)OFBIZ-4781 - entitymodel - entity-condition inside view-link does not work
