To be honest, Blogger is one of the Google Apps that needs an overhaul or an update at least. Most apps are already "Googley" and available in mobile but not Blogger. Recently, it introduced 4 new themes that may suffice enough for an overdue update.  The 4 NEW themes are:  Contempo, Emperio, Notable and Soho Emperio Notable Soho These new themes looks yuppie and millenial so you might want to try one of it. I'm actually using Notable.
