Debug window that just renders text content #24

It should be easy to whip up a view that renders just the text content as a debug view. Either as a Split View in the TUI, or even by using something like DVUI to render a full on debug GUI in a separate window.

Either way, having access to a lot of quick debug info is going to be real nice. Making that a GUI in a separate window that can be enabled with a compile-time flag has a certain appeal to it too.
