I'm with Brenbo in the Autohold camp. Autohold on always, except for times when you might need to make miniscule parking manoeuvres but even then I leave it on. I haven't touched the handbrake in my R since the first week of getting it. I daily have to park at the top of a hill at work and I've never come out to find my car at the bottom of the car park - it's always where I left it.
If you use Autohold feature - on the lower DIS it will show green handbrake symbol to show AH is engaged for instance at traffic lights etc, and then when you park up it will show red handbrake symbol. So a quick visual check is all that's needed. I was a massive electronic handbrake sceptic prior to getting a mk7 - that lasted less than a day.
