Display how you're feeling today via a Retro Video Game Life Meter. Just input how much you want it filled and write a caption to say why.
Since you are using the short code in your post/page I'll let you design that however you wish. If you want it though let me know and I'll add it to the next version.
Originally I built this to use 5 hearts only but I was bored today so now you can have as many as you wish! Just enter the number in the widget or in the shortcode as 'hearts' = '3' and the plugin will take care of the rest. *note: I haven't tested the ins and outs of this so I'm not sure how well it works but I don't forsee any major issues.
