+
+There're some features missing we would like to add (without time plan):

+=over 4
+
+=item LOCK TABLE
+
+The newly implemented internal common table meta storage area would allow
+us to implement a LOCK TABLE support based on file system C<flock ()>
+support.
+
+=item Transaction support
+
+While DBD::AnyData recommends explicitely committing by importing and
+exporting tables, DBD::File might be enhanced in a future version to allow
+transparent transactions using the temporary tables of SQL::Statement as
+shadow (dirty) table.
+
+Transaction support will heavily rely on lock table support.
+
+=item SQL Engine selecting on connect
+
+Currently the SQL engine to use is choosen during the load of the module
+L<DBI::SQL::Nano>. Ideally end users will be enabled to select the engine
+to use in C<< DBI->connect () >> with a special DBD::File attribute.
