Currently, front page post count and archive list item count have to be the same. In my case, for example, the archive page shows only titles, so it can show more posts than the front page, which shows entire posts. It is cumbersome to ask the user to scroll through small lists of 10 items when, say, a category has 40 posts in it. Ideally, I could leave the front page at 10 posts and set the category archive to show 40 titles.
