Overall Very Good

If you are not a web designer but can use CSS you can make appearance changes pretty easily-hopefully I’m not messing up the mobile aspect.
Neg: there are some limitations like blog page, can do 2types of excerpts or full posts BUT, no sidebar option (even though it appears as a choice) it doesn’t work on post page. So problem is if you have say over 15 posts it would be nicer to be able to have posts form columns! Or I could put links to other posts in sidebar widget to have viewers easily be able to scan large # of popular posts, but you can’t
Also slider if you make home page static page, then slider which is great+ appears on both blog posts page and home page, no option to limit that.
PLus: clean (and yet sophisticated), responsive,
