Some extra features

1/ Dark mode (I use "Dark Reader" Chrome extension and your app is very appealing)
2/ Button or tab to have a glimpse of all the Headlines of our post when we are using the Editor (like the Postpace concurrent app)
3/ Ability to change the size font of the editor without changing the rest of the app
4/ improving the contrast of the red-yellow-green in the area KW difficulty only.
