Would be helpful if the column headers on +localpackagediffs would allow sorting of the results.
https://launchpad.net/ubuntu/oneiric/+localpackagediffs shows >500 results (and probably always will). A user typically will be interested in only a subset of the packages, however currently it requires paging through the results (75 per page unless you hack the batch size in the url). Currently it sorts by source package name, which seems like a reasonable default, but some may want to sort by uploader name (so they can more easily find packages they were the last uploader on), package-set, or even latest comment. There may be other sorting criteria desired that are not currently displayed as columns (e.g. time since last merge from Debian, degree of difference from Debian, etc.)
Filtering is also important, and would help address part of the need. For instance, #798873 for filtering by team. However, some archive folks are actually interested in the full listing, but would like to sort on criteria other than package name.
Sorting on heading name is a bit of a hack and encourages people to use crazy batch sizes. It's better to sort the results at the query itself.
See bug 783423 for filtering, we should probably fix this bug at the same time, or possibly that bug is a pre-requisite for this one.
