I was kind of inspired by Dain looking over the crufty KernelManagementHelper (though unfortunately, I haven't yet finished returning the favor).
In any case, I could produce a list of a few classes that are big and ugly and need refactoring. For instance, there are a couple rewritten yet still monolithic portlets that should be broken up into separate handlers for separate screens, and the plugin installer could use review and splitting out of logic like the HTTP connections and probably more... If anyone wants to review and refactor some of these in the post-1.1 timeframe, please let me know -- I wouldn't mind trading. :) Thanks, Aaron
