Which documentation resources do you use most often? (Automation Help, user’s manuals, Downloads section, etc.)?
In fact, all of them that you listed. In the last few weeks, I have also started to use different AI assistants, which are not official documentation for sure but are providing very good results for some types of questions.
How easy (or difficult) is it to find what you need?
If you know where to search, it is not difficult. Everything is about the search engine, and e.g., the engine on the B&R webpage could be better. The future, from my perspective, is the B&R AI assistant that would connect, index, and search all possible resources.
How would you rate the usability of our Downloads section?
3/5 
Any features or improvements you’d love to see?
Online documentation, easy to access, easy to search with possibility to store my local copy based on my search for offline use (if I’m somewhere where is not internet connection)
What works really well that we should definitely keep doing?
From an official documentation point of view, a huge step forward was moving AS Help from offline to the online version. A small step with a huge effect. Moving documentation to the 21st century
Bonus question: If you could wave a magic wand and change ONE thing about our documentation, what would it be?
As mentioned many times: an AI assistant I ask my question to, and it provides me with a valid answer with a link to resources, no matter where it is stored. We can learn from IT world, there are great trends we can follow.
