MTEntriestoMTEntries days="7", so if you haven't posted for seven days when the Main Index gets rebuilt, you're suddenly faced with an empty page. I doubt anyone would mind if the default werelastn="7".- The "Stylesheet" template is a regular index template you have to rebuild. I use the "Link this template to a file" feature to link the template directly to the styles-site.css file so changes are made immediately at edit time with no rebuild. There's no template code, so it doesn't need built. (Defaulting like this would lead to "Template code in my stylesheet is not evaluated" complaints if you made that no longer so, and I'm not sure you'd end up with fewer total complaints.)
MTEntryID-based permalinks. You end up finding why they're bad much too late, namely when you want to import your entries to a new database, and find you can't because the numbers changed. Radio UserLand had the same problem, exacerbated in that you had to renumber entries to postdate an entry, too. Fixing this would require a measure to not publish two items at the same URL, which is a little more work but would be nice in general.
Ehsan Mazloomi's Flash guides to installing Movable Type remind me that Movable Type doesn't default to publishing in UTF-8 either.
