Why don't you let the end customer decide that, besides the point of being an administrator is that you can modify every aspect that cannot be done as a user. If you had a backend demo, this would have discouraged me from buying your app. There are a lot more features which are missing and a lot of things which just don't make sense
How do these changes sound: 1. Make all fields editable by the administrator in the backend.
2. The main menu item seems to only display questions from the root category and i think that should be changed. For example on your site, "All Categories" page only shows questions from "All Categories" excluding all child categories. In my copy of community answers, the root category shows all questions grouped in categories.
1. Will do that, the fields that could be added are user, (username and email in case of guest question), created and last modified date (not sure this can be edited). The other fields are currently editable.
2. This is not true. Home page shows all category questions unless you select category in menu item configuration (as of version v1.8.6). If you select category in menu configuration, it will filter questions from that category only. Since there are not many questions in other categories of this site, you are seeing questions only from CA category.
