Just like in Google Dictionary and Grammarly, when you double click a word it shows its definition.

Microsoft Office Extension can fix grammer issues in Google Docs but Editor can't. That is weird. Also, if you put your own word, be able to add to dictionary. Be able to ignore or put that once for a word.

If you frequently write in two languages, like I do, Editor is too cumbersome to use. It gets in the way more than it helps. It takes a few clicks and scrolling to switch languages. Switching should either be automatic based on detected language, or at least give you on-the-fly switching between languages you select.

I usually type in English, Spanish and French. Instead of changing the settings prior to the use in any of those languages, it'd be great if the extension could detect the language automatically (like Google Translator does).

I've noticing that the text in uppercase is not being checked by the editor

The Editor browser extension identifies two spaces after a period as not being correct per my settings. But there isn't any option in settings to adjust this.

right now, I think the only way to access the Editor is to spell a word wrong. You should be able to select a word and get synonyms for the word.
