AgitatedDove14 Wow this can go many different ways actually! I didn't think too much about where to place it too deeply. I just thought a comment section under tasks might be helpful but you're right. It might be too granular. But an experiment wide thread might be nice, same with project level too haha. Maybe.... an entire separate "forum" module might be cool (a whole new icon on the left hand side below worker/agent button) where people can do @'s for experiments/projects/tasks and even comparisons (basically url links really ) where you can create your own level in some kind of sense.

Also, by "address bar at the top", i assume you mean address url right?
