We need to have Project name (Title) as one of the items that can be added as a column. This is currently not possible, although Title should be regarded as one of the main parameters of a project.
Additionally we would need to have the name of the 'Provider' visible in the view. When you choose 'Workflow State By Language' you seem to be able to choose the 'Provider Name' as a column, but the only element you get in the column are the document names. By hoovering over that document name you then get the name of the provider, linked with the target language. But you have to hoover over every single line to see the name of the providers. Filtering or sorting, based on the name of a provider, doesn't seem to be possible.
