Version 1 of the “Datagrid2” had support for text-filter for enum columns. This was a great feature (imagine a enum with _many_ entries like a country list) because the user just types in some letters ang gets the filtered results.
Sadly this feature has been killed (for what reason?) with the update to Version 2.
Under the line after the update:
I hope that this feature will be re-introduced quite soon!
