Having just got a Harmony, the first thing I've noticed is that I frequently screw up my existing account trying to configure for various devices.

To facilitate that, two features I think would be good are based on a couple of other comments here are as follows.:
1. Multiple profiles - my working one and my experimental one. I would assume that I would have the ability to copy one to another. Also, delete function for the profile. Finally, a replace/append function for adding profile data. Ie, when I finally get a device programmed perfectly, the ability to append it to an existing profile rather than have to replace everything else there too would be great.

2. Copy a profile to another account. This goes in line with helping others start their setup too. A site like this could really promote that type of sharing of info too.

What do you think. Should we ask this of them.

Dave:

You can set up a second account for experimenting with by signing up with a new e-mail. Use yahoo or something like that to get it. You cannot switch stuff between them automatically, but it will help to prevent major screw-ups. And, you can always copy the XML from one account page to another.

And I would like to see your other suggestions invoked. ... Mike

Mike,
I know you can duplicate a file, but I'd like to be able to copy "working features" between my active profile and test. Once I get something working right, copy it to another profile. It also would facilitate sharing with users here.
