Beautifying the titles
I have noticed some people enter the title in ALL CAPS or all small charaters. This doesn't look very nice. IMO the best way to display titles is having first alphabet of each word as capital. So, I managed to display that on single ad listing page but am not sure how to make it look the same for widgets - Top ads etc.
Replace <?php the_title(); ?> with <?php echo ucwords(strtolower(get_the_title($ID))); ?> in single-ad_listing.php
