We have a few things we can try like: • Changing the "a" to have a hat like normal fonts • Using a system font for Latin text and keeping the bundled Japanese font • Adding an option to use the bundled font or system font But first I'd like to know what you think!

A few quick tips! • Once you enable the add-on, a little "puck" appears that you can use to point to words • You can also try tapping on words to look them up • Double tap the puck to reverse its direction: up vs down • Tap the puck once to temporarily disable it

You can see the new compact popup in action in this video:
