Forum categories forced list


I was wondering if it would be possible to implement an option to hide the categories when using the main one.

For example, I’m active in the Ruby forums, and I’m interested in ALL threads, I don’t want to have to scan through the categories to see all threads. Of course the full list is available below these, but it wasn’t the case before (all threads were on the same level and categories were available via a drop-down list) and I was wondering if it was possible to hide these categories in the future, or at least give an option in our profile to hide them?

Thanks for reading,
