It would also be nice to see what's already mapped, even for the built-in keys. Maybe an option to dump out the user-programmed keys, the built-in (and un-remappable) keys, or all of them together. To be honest, I wasn't aware that any keys were automatically programmed in the device and that led to some of my confusion. I see now that you have a FAQ entry about Harmony that says:
Do you play well with harmony?
Yes, very well. In the latest version of the firmware, we added a default XBMC profile so as long as you are running that release, your flirc will work with the harmony without any additional pairing.
That makes it somewhat clearer, but some feedback in the app (similar to what Videonisse is requesting) would be very welcome.
On a completely unrelated topic, this website very often hangs when I try to post. It just did it again (the fourth or fifth time it's happened on different days), and like always, I see that my post has indeed been posted when I manually refresh the page. It just sits there "Saving post...", sometimes with an animation, and doesn't come back. This is with Chrome on my Mac and I haven't tried it with another browser or machine yet.
