TableView, Search, Categorize and Access all and any FieldType/Source

It would be great if it were possible to filter and customize based on every field-type,

but especially to access fieldTypes created by integrations.

Example issue:

I have an integration and want to have a list of devices with IP-Addresses.

The integration already displays a Field "IP-Address" in imported entries, but I can not access that.

So I have to use or create a new fieldType with "IP-Address" that I then can put on the TableView.

That results in a redundancy which creates extra manual work.

Now I have a manual and an automatic(integration) IP-Address value. If one gets changed, the other does not.

There goes the database consistency.
