I was making a macro that's triggered by an URL. I'll be using this URL a lot within a file (with different parameters), and I wanted to make the URL as short as possible to keep the file readable.
I thought "It would be good if, instead of writing kmtrigger://macro=Name+Of+Macro&value=Value, I could write kmtrigger://m=Name+Of+Macro&v=Value. I should post that as a feature request on the forum."
Fortunately I tried it out before posting, because it already works. A great example of one thing I love about KM — it's full of little affordances that anticipate the user's needs.
