I am using version 2.2.7 and it looks good on my development machine. :D I like this, it is good. :D

I haven't dug down into the code at all, I'm just looking at what is set up for ease of use. I didn't see a setting for the linear / hierarchical view when I'm looking inside of a topic. Is there a setting in the administration panel to affect this, or do I have to build it myself?
