As a new dev blogger, my tool box is a little, er, sparse. I've been learning markdown, which is nice for formatting, but then I see other people's beautiful looking posts and I think - I want their tools, their methods, their flare. As part of my ascent into blogging nirvana, I thought I'd spark a discussion and see what others think.

• Screenshots - I've seen images that blur all but the important stuff, others that highlight/number the relevant clicks and inputs, etc. In my StackOverflow posts, I've used... Paint... Probably time to upgrade, what would you suggest?
• Code examples - There's the gist thing from github which I haven't explored, things like codepen and jsfiddle for web stuff. Of course I can \`<language> in markdown - what else? Any pro tips?
• Productivity boosters - are you composing your markdown in the dev.to editor or is there a better way? Live previews? Templates?
• Other 'nice to haves' - Any other wizzbang I should consider to make my posts POP?
