i have set my posts to be displayed in 4 columns – 11 posts to show. Whith “featured post” checked this displays 3 rows of content. When one proceeds to the next page in the pagination, he/she gets to see 3 rows again with one post missing (11 posts without featured post).
for me it would be logical to reduce the number of posts on the first page by one whenever the “featured post” option is checked. Maybe add a little hint to the option, so that people know what’s going on 🙂
