So IceChat comes installed with the Highlite Plugin by default.
There are also 4 other plugins available on the website.
Google Plugin - Allows users to type in !google 'search' and it will return the top 5 results
Buzzen Plugin - this is used to automate logging into the Buzzen Network, as it requires a username.
Twitter Plugin - allows you to follow twitter feeds, posts them to their own @window by name
Channel Monitor - Creates its own panel under the input bar, and shows latest messages from selected channels
If you see any problems with these current plugins, or have ideas for more, feel free to post here.
