Here's another thought; create an object/sprite underneath the text that can be use as a click/touch option. Useful when you want to click on the notification and go to another layout or display more info.
In a way, similar with what you have now on the side (very nice feature by the way) but underneath. Like "click here for more info" type of situation.
GRATE plugin by the way, very useful in creating notifications, fast, easy, clean, and very adaptable.
