Good implementation! Rated 4 out of 5 stars
This is really good code to start customizing the web browser to resolve one of the oldest UI issues: Web pages that are way too wide to read comfortably. There are many such pages--with over 100 words per line, for example, I've modified v1.12 so that page width stays around 512px. Horizontal scrolling is now minimal. The modified version works better than Opera's "Fit to Width" feature. Thank you, glzaou!
