We are in the verge of releasing a new feature that will change the way owners customize their Nabble applications which will allow you to customize almost every aspect of content/design so we have not been updating our documentations for some time now.
Anyway we try to make all applications as intuitive as we can and sometimes when it is not as good as it could be we have a strong community which points out what must be improved and we do it. So I hope that if you just give it a try you will find that everything is very easy and straightforward to use.
Any problem or question you have you can come here and ask for support. Also you can search here to see if your question hasn't already been answered so you can know the answer immediately.
In addition you may want to request premium support where we will be able to assist you customizing and setting up your application even further. For more information you can access the link below:
