I've searched and can't find... how to keep the Text and Font manager (ctl + shift + T) in the same window as the canvas. How do I keep it in there? I swear I've had it in there in the past; I'd like to manage the work space by keeping the windows in one window.

It's one of the few dialogs that can't be docked. And I know what you mean -- it drives me crazy. I did see a bug report, or something somewhere, so it's been requested to make it dockable. You might try the current development version, if you can handle the possible instability. Maybe it's already dockable??
