Evaluate UI test coverage + prepare summary

To make our QE work more transparent, it would be nice to:

1. create a list of all features of Fuse Tooling (group them into topics) --> DONE
2. create a list of all UI tests --> DONE
3. map UI tests to features/topics --> DONE
4. make some conclusions --> DONE
   1. well covered, partially covered, not covered feature/topic
   2. suggest new UI tests
