Not everyone is a fan of flashy sites. Most professional websites keep their designs simple to keep their visitors satisfied with their experience. But if you need your WordPress site to look more flashy, you could always add cool page transitions to it. WordPress Page Transitions is a cool plugin that adds page transitions to your website.
WordPress Page Transitions requires flash to be installed on visitors’ computers to work. On mobile devices, it does not change the behavior of your site. The transitions do bring a cool effect to your website, though they could turn off your visitors who may be coming to your site only for content and not cool effects.
Should you install the WordPress Page Transitions plugin? It might be worth a shot if you are looking for cool effects for your site. The plugin is currently in beta stage.
