Thank you for answers.

Duplicate entries in the old version worked via right-click. That's the way I used it and in the new version it is cicked out. Ok.

What bothers me the most is the speed of the new version. It takes a long time to write something into the search field, because the search field sometimes does not react to inputs for seconds. Will this ever get better?

The new version is buggy:
a search for r+v  (letter followed by a special character) does not return a result.
It's really annoying that it is impossible now to duplicate entries anymore.
