This has been an issue for at least 3 releases and is still not fixed. it's a significant issue because viewing a table and then switching to the SQL generates the cleanest DDL (better than DBMS_METADATA). However, the partitioning clause has to be written by hand. This also affects comparisons between schemas/databases because you get tons of false positives when the number of partitions is different, even when the DDL is the same.

Frankly, I would prefer this fix over any superficial updates to the icons, or the addition of a dark theme.
