I have a cluttered miscellaneous bucket as well. It seems like the miscellaneous bucket is a special case because the history of items completed has no relevance to the items yet to be done. (In viewing a specific project, the items completed are relevant to the items yet to be done.)

I fear the Miscellaneous bucket is going to require regular, manual pruning in order to be useful in the Planning mode. The suggestion of filter controls tied to buckets is a good one as a general case, but I would be happy with any mechanism that would suppress the completed items.
