That's a great app! Very nicely done!!

As for feedback, I'll offer some suggestions:

* I'd like to see an "Other" added to each of your categories.

* It'd be nice if we could select the weight standard we wanted to input, like ounces or grams.

* For water and liquid fuels I think it'd be good if we could just enter the number of oz or ml and the weight of our containers for them.

* It'd be nice if you could create a "Print" CSS file so only the gear list and weights are printed (your logo would be okay there too ) and it would generally fit on one page.

* And, of course, it would be nice to be able to email or "Share" a list with friends.

* I suppose it might be fun to have a "Demo" list pre-filled with items so people could review and play with them. Perhaps you could do several, like an Ultra-light, Light, Standard, etc.

Anyway, I think it's pretty darn cool. Thank you for sharing the hard work and effort you've put into this, and please keep us posted on your progress and any new features you add.
