>But I also get an “event” for every uploading of a file to the system
Problem confirmed, it will be fixed in next update.
>Can an option be added to allow for a “one click” add event?
Functionality is supported by client side so we will think about adding related option to the admin panel.
>Could you extend the “Allow users’ groups to edit events”, to allow users according to their “level”
Will be added with the next update.
>3) Edit some one else’s event.
It will require a more serious customization. So most probably it will not be added in next release, but will be set as middle term goal.
>>I would also like other things
Existing version lacks many useful options for sure. But we plan to improve it in future ( thanks for feedback by the way )
The next update will be released in next two weeks.
