Thanks for taking the time to check it out. This was my first real post of my own macros on the keyboard maestro forum, and I duplicated some of the relevant ones here. There's a lot to keep track of and one thing I completely forgot was that the developer, Rinus, had sent me a beta version of PlugSearch, so the "universal" option won't be in your version I'm afraid. Apologies for the oversight. I'm sure if you emailed him, he'd be happy to send you the beta. I'm tempted to send it to you myself, but I don't think it's really my place to do so. Maybe he wouldn't mind, but maybe he would; I'm not sure on the etiquette there.
As regards the library patches, you'll see in the main thread I linked to above that I no longer use Alfred for that. This was mainly because I realise that not everyone has it, so I tried to come up with a method that's more universally applicable. Let me know if that method works for you instead.
