Would it be possible to change the admin interface so that when you log in you go to a 'welcome page' (with statistics about your blog, number of moderated comments, links, etc.) instead of going straight to the 'post new entry' page? I think this'd make WordPress a little bit more friendly while providing some useful information when you log in.
PivotLog has a similar 'Overview' feature when you log in (as do most other blogs). It'd be nice to have this as an option you can turn on or off, at least.
