Events Cannot seem to identify 30 minutes and feature request

Ok, I am on 3.4.1 (Single Site) and the latest Events+
I am doing a recurring event and setting the "Event Duration ____ Hours"
I am trying to set "2.5"
The script cannot seem to identify the 1/2 hour it simply gives it a 2 hour time frame.

FEATURE: (If it doesn't exist yet and I missed it??)
Different categories of events have different colors when displaying on calendar (All my colors are the same? Not very good for those of us with more than 1 type of event. XD
