Dieses Plugin funktioniert einfach toll, nichts zu meckern! Die Installation geht superschnell. Das Design paßt sich der Umgebung gut an (bisher ein Mal eingesetzt). Da macht es wenig aus, daß es so gut wie nicht stilisierbar ist. Dafür spart es dem Anwender viel Zeit! Freundlicherweise hat der Programmautor die Option verwirklicht, daß die Platzhalter in den Feldern abschaltbar sind. Sehr empfehlenswert! This plugin just works great, nothing to complain about! The installation is very fast. The design adapts well to the environment (used once). It makes little difference that it is almost non-stylisable. This saves the user a lot of time! It is a good idea that the program author has implemented the option that the placeholders in the fields can be switched off. Highly recommended!
