Thanks, Beerstalker, it's not that it would take too long to make changes. The One is my 4th Harmony remote, and I'm slightly burnt of setting and finetuning them, which is a hobby in itself (I've done it all, including adding Hex commands in the hidden IR analysis center)
After realising the IR2BT profile doesn't include the button icons, I included a PS3 device in the activity, so that's solved as well.
As for discretes, I don't want them in the PS3 and 360 activities. Sometimes, when playing a game, I simply want to check what's on TV, pausing the game. A discrete Off would be annoying. Instead, I prefer to manually switch off the consoles when I'm finished. However, I'm using a fake discrete On for both consoles, adding the 1 command at the start of PS3 activity and the Xbox command at the 360 activity. If I return to a console activity, the fake commands are harmless if the consoles are already on.
Of course, I appreciate the efforts made by the IR2BT & PS3IR-Pro creators. It's just that, should the PS3 include discrete power commands, I would simply not use them.
Finally, I was wrong, the IR2BT colour commands do work with the PS3IR-Pro. After trying the Pro colour commands without results, I realised I was doing it the wrong way. Resident Evil Extinction shows the colour commands in the Chapters Menu, where I was trying them. However, bookmarking only works in playback.
