Thanks for compiling this list! Many of these features are crucial time-savers for anyone wanting to step up their writing.
I also want to add that "Snippets" can be used in conjunction with Templates to save portions of posts you plan on using repeatedly such as banners or footers. This is often missed, but it's even available for use in comments! Just look for the three sheets of paper icon in the upper right corner of a comment box next to "GIF".

Thank you! I've never used that. I'll check it out.
