Here is a link to a beta, err, an alpha to try. :)
Let me know if there are any serious issues with it. If I don't hear anything, I'll release an official build on the main site soon thereafter.
peekko-beta-0.3.0.xpi
Added button to show the most popular channels
Added Dutch localization
Fixed international suffixes (e.g., #)
Please add the bugs related to this beta on the wiki.
