Just had a bit of time to update the extension. The update is live in the Chrome Web Store now, if you're already using it, you should get the upgrade soon.
What's new in Version 0.3:
- Added new traders (now: MTGox, TradeHill, Bitomat and BritCoin)
- Clickable links to the traders (directly from the popup)
- A few under-the-hood improvements
@jibjabz The amount of text on the badge is limited by Chrome I'm afraid, so can't do much about that (other than making it scroll, but I don't think that's a good idea :-)
If you're using this, please consider a donation. Chome Web Store currently reports 131 users, but I've only received 0.01BTC (thanks, whoever you are).
I'm currently working on some more features, I'll update this thread when they're ready.
Keep up the comments/requests/suggestions.
