I think I can't renounce to this feature because it is really cool. I'd love to know if there is a page or a link to a forum section providing some good examples (5e OGL Sheet) of some macros (normal attacks, sneak attacks query etc) as my next session starts tomorrow and I'haven't time to learn the syntax but I'd love to surprise my players setting some power card macros for 'em. Thanks.
Additinal info: currently I'm using alter bars script
You can find some examples of those types of macros (attack macros using alterbars) in the last few pages of the latest PowerCards thread .
