Rosemary Orchard, writing at MacStories:
An action is something you can add to Drafts to give yourself a button (and optionally a keyboard shortcut) to do something. What that something is, is entirely up to you. From integrations with WordPress and Dropbox, to scripting and custom HTML previews, the combination of steps you can combine to do your bidding is positively mindboggling.
Drafts for Mac ships with five action groups, which by themselves greatly increase the power of the app; these include: Basic, Editing, Markdown, Tools, and Processing. The names of these groups are fairly self-explanatory, and they deliver plenty of punch so you can easily do more with Drafts – even without looking into the wealth of actions available in the action directory.
Drafts is crazy powerful, and I’m excited to see it bloom into a full-blown Mac app its iOS most important features.
