I like that it is easy to use, you can create tutorials very fast! It's free for basic features but as soon as you want more bells & whistles they ask you some additional costs which makes sense since this software was created by people who actually work full time at creating such amazing content.
The interface could be better designed so we don't have to learn how things works when using our first few times. We are working together with other companies from around Europe (and even outside) and also students all over the world and sometimes there might come up situations where one of us needs help or advice. Thats why having access to experts through forums etc would make life much easier than going into contact with someone locally.
