Conditions and tracking

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.

The individual tokens can be assigned graphical condition markers and a numeric counter with a simple click. Integrating the effects of those conditions is something usually handled by well-crafted macros or just tallied in your head as you roll normally

I saw the graphic overlays, I did not see the numbering though. That should come in handy, thank you.

No worries. You use those by pressing a number key with your mouse hovering over the symbol you want.
