Description

I joined a table layer to some geodata. Now some features got new attribute values while others got NULL values.

It would be very handy to be able to quickly assess the success of a join.

For that one would need to see:

- The total number of features on the parent layer (the one joined TO)
- The number of features on said layer for which a matching row in the JOINED layer was found

The Layer Properties -> Joins dialog could get a new column for that, showing e.g. "123/5000" or "5000/5000". I added two rough mockups.
