a custom primary key. It is safer to use the .pk notation.
Fix incorrect function call and replace one more explicit .id with a
.pk.
Adding index to columns that are being used to query for data.
Add pagination to list view, otherwise it's a very long wait to load all
strings.
Fix a table rendering issue.
