`org-mode` used with Emacs is the tinkerer's dream playgound. Apart from the basic markdown stuff, there are so many wild things you can do. For example, org code blocks are not just the basic markdown code blocks that show formatted code. Org code blocks can actually be executed and can show the output of the code, inline. So you can write code blocks (that may include data found in variables/tables/etc elsewhere in the org file), then "refresh" your org file and all the inline outputs of the code blocks will be updated.
