I run a couple of 5E games online and I've been looking at Roll20 for a while.  I'm wanting to give it a shot with one of my groups but one thing that I'm wondering is how are you tracking various conditions (Blind, Poison, etc) and their durations?  I'm looking for a way to do this preferably without scripts and in a way that gives me enough information to remember exactly what I need to do for each one.
