Dear Achim,
The beta app is working fine and more over it also support's normations. The speed of app is also very fast and smooth.
Please try to make some thing to notify user's about new dictionaries. One of the user requested for Telugu dictionary via play store review. I've posted Telugu dictionary. but, he might not get to know about it until, he rerun the dictionaries list. So, kindly make some arrangement to notify users.
