Its a good improvement. I think an action that has more static text my help, maybe something that is like a form letter, something like:
On %Variable%Date% you purchased our lovely product. You can find out more at (%SafariURL%).
Or even instead of using strict markdown (which is confusing because the only “text” characters are brackets with their own meanings, expand the text to something like:
Look at this neat article on %FrontBrowserTitle% I just saw at (%FrontBrowserURL%).
Basically something that makes it clearer that the tokens are frequently inserted as placeholders in text.
I suspect someone who doesn't know markup is going to be confused by the meaning of the brackets in the current example and think they are part of the token processing.
