Portal to the Universe font size

The font size needs to be able to be increased for those of us that have visual challenge. Other than the font size the App rates 5 stars.

All the info I was looking for on the cosmos. For a good star gazing/constellation identifier app, try "A Starry Night."

For Want of a Nail

As good as it is to have all the headlines collected in one app, it's nearly useless on iPod Touch in its current state:

(1) Must add a landscape view to the Web browser, because the text is too small to read when limited to portrait.

(2) Browser needs to be faster.

(3) Crash upon closing Web pages must be fixed.

Currently useful only for skimming headlines.
