Hide and Search
It used to be that the bandwidth/packet loss bars were always visible, then LL covered them up with Search but you could uncover them by unticking a box in Preferences. Then they did away with that, and I didn't know where to tell Enjah to find it one day when we had need of it.

I spent some time poking through the Debug Settings and found it again: scroll to ShowSearchBar and set it to False.

Hear that, Enj?

Also, I haven't posted about this before, but if you are using a new viewer and want to enable http texture retrieval (which speeded up the map immensely) look in the Debug Settings, find ImagePipelineUseHTTP and set it to True.
