The snippets feature for quickly adding often used phrases and short-form copy within emails would really benefit from supporting rich media like images. This would mean regularly used screenshots, diagrams, or graphics could be added with accompanying text to the snippets library saving countless hours for marketing, sales, and services teams.
I've recently built images-in-snippets functionality into my chrome extension "Snippet power tools".
You can scroll down to the features section to see a demo.
It allows you to insert any public image as a url into a snippet - then when you go to use it in the helpdesk or inbox it'll swap the link out for the image you want.
Way easier than having to keep all your images on standby so you can copy and paste.
