I finally got the chance to set up my Flic hub, after having used an old Nexus 5 (and Tasker) to handle the household Flic duties, and I am SO HAPPY.
I was able to use the http request action to handle the music tasks that were previously handled by a Tasker Plugin (such as 'play a random album from my collection in the loungeroom') and I am super happy with the near-instant response that the hub provides.
I also use the Flics to control my Hue lights, so the improved speed makes a big difference in that situation, too. It's all so snappy now!
So I just wanted to say thank you: thank you!

Oh man. I hope that the 'change configuration' feature comes, too - I use it every day!
