Make users be able to write correctly on different languages and improve UI (make something like Grammarly, but international)

Spelling suggestions in the browser extension should be shown on Hover rather than a left click.

No reason to have to have us go to the extension website and then click the feedback link

the wavy red underline of Editor Browser Extension remains after emptying search box.
repro: in a Yammer community on top of the page there's a search box, search for a word not known by Editor Browser Extension or misspell a word. As expected, it'll wavy red underline your word. Then click the X to empty the search box. Search box is empty now, but wavy red underline remains.
Same goes for blue underline for grammar mistakes and purple underline for refinement suggestions.

Current Wordpress editor does not refresh underlines of wrong text when you move the section or paragraph. It looks messy and does not work correct.
