Thanks, that's great news!

Ken's suggestion of holding the OK button to go into split mode is also very helpful in getting an entire column to fit the width of the screen.

Yes, the four segment grid is very useful for 2-column documents.

I agree that the lack of continuous zoom is disappointing. At least a few more zoom levels would be nice. I wonder of there's a way to hack the firmware update and replace the 1600%, 3600%, and 6400% zoom levels with more useful values.

I hope that they have added continuous zoom level to the new firmware. I haven't had the chance to check it out yet.

Since a lot of technical documents contain images, or are just a series of scanned images, you can't just convert them to text or use Calibre. The only option is to convert the pages one-by-one to images, edit them, and convert back. A method like this might work:

Thanks, I'll try it out. I used pdfcreator to change the page size, but the JBL ignored the scaling.

Cheers,
