Tabs are just another form of MDI, which everyone in their right mind has been running from lately. Why? Because as the OS window management tools get better (Expose, Aero Peek), it makes less sense to reimplement the features. Moreover, UI's designed for "all maximized, all the time" don't play nice with multiple monitors, which are becoming fairly common. At the very minimum, tabs should be "tear off", and should reveal themselves when using Expose / Aero Peek.

It seems to me markdown (http://en.wikipedia.org/wiki/Markdown) has a much shallower learning curve than latex, and it is already supported by several wiki systems. All you would need was a html -> printed page post-processor, which may already exist.

Or almost 8 foot by 3 foot. That would look FANTASTIC above my couch.
