During testing of jsc#SLE-2995 and playing editing form.yml to create different visualizations, it was found that:

- When no formulas available application could help user more with some hint or displaying empty list instead of closing.
- After applying formulas, application should return back to list of formulas instead of closing, wouldn't make that more sense?
- Cannot navigate among Section items once and error is triggered (i.e.: item restrictions error avoid to continue navigating in Section area).
- Once an error is displayed focus does not come back to the (first) offending field.

Expectation:
Some improvements in usability, at least consider one of them, not closing the application after finished and coming back to the list.
