juardo,
I have found that for centering the column, equations, or figures when zoomed, the Jetbook does have an almost-continuous scroll option. If you hold down one of the scroll keys for a second or so, you will find the reader scrolls in much smaller increments than if the key is just pressed once.
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.
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.
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:

I finally bought a Jetbook lite. It's great for reading e-books (txt, prc, ...), but a little limited for PDFs. I've come to the conclusion that a 5" screen needs a pdf reader with refow (like Foxit mobile).
Also, a continuous zoom and a more continous left-right scroll are a must. Otherwise, you cannot properly center equations and figures. It is a shame that the JBL does not already have proper zoom and scroll, because they are really easy to implement (unlke reflow). The JBL already does the 'fit to width zoom' so it can already zoom at any desired zoom level. It's just not available to the user. I hope that ECTACO firmware guys implement appropriate zoom and scroll soon.
Otherwise, we will have to use the JBL with Android someone is developing in the forum  .
