The context: when I have a big blogpost to review, it often takes a long time and a lot of back-n-forth in the post.

New solution: two windows, possibly on two monitors. One window shows the post editor; the other displaying published post.

Traditional solution: A single wordpress post editor

• it uses only part of the monitor real estate
• I constantly worry about accidental edit like deleting a char. In 2-window, I spend most of the time in reader window, and switch to the editor window only briefly.
• during the /lengthy/ review, I need to Save (my changes) many times. Each Save is slow and disrrupts the flow of reading. In 2-window, I tend to Save slightly fewer times (less scolling in the editor), and the reader window is unaffected.
