The name dictionary is a great addition, but a little bit of explanation would be nice (eg. in the settings panel). I mean what are the letters stand for, like... f: female? m: male? u: unisex? g: ?? s: surname? p: place?

This app is great. One feature I would really like is a setting to add a delay before the popup appears. I don't need it to look up every word as i am moving my cursor across the page, just ones where I hover my cursor over the word for like 1sec or something.

The text in the popups is a bit too small for my liking. It would be nice to be able to specify the size. Just started using it, but it looks fairly helpful.

Amazing little tool. Simple to toggle on/off and gives several readings for any Japanese you may bump into. Highly recommended!

I couldn't get by without it. It is a bit annoying at times as it constantly pops up so you are forced to turn it off and on when browsing a page.

Useful, but really annoying. I've been using this and rikaichan for many years and the most annoying aspect (find several complains about this) that focus is lost and potentially part of your message gets deleted whenever the popup is shown makes it almost impossible to use.
