I had to modify index.php a bit to get this working. Please backup theme.
Theme will show now the excerpts on front page and other pages, and it will skip short codes, but you need to enter excerpts manually for each post.
If you don’t know what excerpt is, or how it’s done, just open “En Suite Bathroom” post and scroll bellow the post editor. You’ll see a field “Excerpt” and enter there post description which will show up on front page. Excerpts are hidden by default, and you can enable them in “Screen options”.
