Best extension for non Japanese speaker! I have been using it for many years now. Thank you!

It's the nicest popup dictionary extension I've used so far, but there is currently no option that I can see to have a monolingual dictionary, so I find myself having to return to Yomichan.
Would be great if you're able to add this feature in the future.
