@RianVDM hmm. that is a good question! I am not sure, though @manton included a bunch in his longer post announcing the change. I'd imagine if you host on micro.blog it would be picked up in longer posts while self-hosted might be more of a challenge since just the title and link come over to MB. Maybe Manton can confirm...
@smith in MarsEdit, on the post compose window there should be a Format dropdown in the toolbar. Open that up and click Customize. Here you can add your macros. First I created a Group (under gear icon) and then added each. I just added the emoji in the Opening Markup box for each macro. Hope that helps!
