Right now the theme has this feature: "To show only your four latest posts (with a Featured Image above each one, of course) in a neat grid on your home page just visit Appearance → Theme Options and click the checkbox there."
To have it even more practical, because this is a really great theme, I suggest to be able to choose the category of the latest 4 posts to be placed in this grid.
Another idea is to be able to select if you want the latest 4 posts or latest 4 pages. This would actually be even better.
The blog I need help with is mihailmusat.ro.
