Hi zafer and CAA.
Thank you both for your answer, your feedback is appreciated.
zafer:
In deed, good examples are always useful.
CAA:
Linking related resources (like AT command guide and ADL guide) is a good idea to me, it could give a better view of the different solutions to achieve one’s task.
Finally, you seem to agree on search capabilities as on useful feature, and pdf a good file format.
I hope we can get more interesting ideas and opinions.
