hugbug, Thanks for creating this. It works fine for me.

But I have a request - is it possible to automatically close up the gaps left by deleted entries in the Additional Buttons list? I've been taking default device layouts that have way too many non-applicable functions and deleting everything but the ones I need, so I end up with 8 or 9 functions scattered over a range of 50-60 mostly-empty slots. The Harmony site doesn't remove them when you save the button configuration, so the only way is to painstakingly click each one up the list one slot at a time until it reaches to top.
