Question Is it possible to remove the margins in book reading mode?

Hi,

Just got my kindle 3 firmware 3.02 no hack yet.

I notice the kindle is capable of edge to edge display in its web browser. I want to remove the margins in book reading mode. I also want to hide the location bar at the bottom and have it shown only when I bring up the menu. I have poor vision and am using the third or fourth largest font size, depending on the font, and I want to maximize the amount of text on one page given my constraint. I am already using condensed font and smallest line spacing.

Is this possible?

Thanks in advance.

Thank you.

Oops I put a thumb down icon in my original post. Thought it was a question mark. Like I said I don't see very well . Post edited.

Is it possible to make this work with pdf-files too? It works with my mobi files, but not pdf.

No, you'll have trim the margins of your PDF file. (Supposedly, I try to stay as far away as possible from PDFs).

Thanks for the replies.
A few questions concerning Calibre:
Some of my pdf files won't convert to MOBI. What could the reason be? DRM issues? And if so - how to tell? Conversion settings in Calibre? This is an example of an error message when trying to convert a pdf book to MOBI:

Okay, I just figured out the answer is to downgrade to version 0.7.19 --> Link

UPDATE:
I modified reader.pref again and this time the value is not reverted. maybe last time I was in reading mode and the reader restored the value.

I followed this instruction to modify "reader.pref". Then I ejected kindle and re-connected it. To my surprise, in "reader.pref", "HORIZONTAL_MARGIN=" becomes 40 again.
How could I prevent this value from being reverted by the kindle system?
Thank you so much.

By making very sure that you are on the Kindle's Home screen when you plug it in and make the changes. If you have a book open when you plug it in... the changes won't take.

You can also set Justification to Left instead of Full, which should make the larger text sizes less annoying: http://www.mobileread.com/forums/showthread.php?t=99661

The trouble is that Kindle 3 adds about 15 - 20 px-wide additional margins when viewing pdf in landscape mode, which I find annoying. Isn't there any hack to remove them? Pdfs typically have margins already, so this is a waste of space. (Of course the margin on the bottom must be there because of the progress bar, but not the other three.)
