I just made a SGDK2 toolbar compatible with IE and Firefox.
Main Features:
1. Search engine powered by google
2. Quick links to various pages related to SGDK2
3. A news ticker to display...well news... like new releases and stuff.
4. A email notifier-tells you when you have new mail, instead of you having to check all the time. (complatible with GMail, yahoo, hotmail and POP3)
5. A weather notifier, which you can switch to your area and it tells you...the weather. lol
6. A chat-room, click the button, put in a name and click ok...a very simple chat program.
7. Message sender, send messages to EVERYONE with the toolbar.
