1) One big advantage of the new S/W is we no longer have to explain (over and over) the command propagation and custom command regrouping workarounds :-)

2) Akirby, I hope you kept your old 659 Harmony remote. You can use it to setup a Start activity macro, and then teach it to the other Harmony remote as a single command name in RAW mode. Also the Activity Start macro supports delays. You are no longer at the mercy of the latest inter-device/inter-key delay bug. I had to use that technique for some of my lost pseudo macros. The delay became very handy for some of those macros. If you decide to use that technique, create a new account, set the device power settings to always on (so it won't send any power command), set all device delays to 0 ms so that you can control them via the Activity Start macro, and use the Generic activity type (under Utility) to allow selecting "I don't need to set the input" so it won't send any input command.
