I am writ­ing a book. And I am writ­ing a chap­ter about UI de­sign. And why not use the In­ter­net?

So, go ahead and tell me all that's wrong with this di­alog!

For ex­am­ple, I don't like the dead space at the bot­tom-left, the dif­fer­en­t-­size of the "Close" but­ton, and the mis­align­ment of the icon­s.

Are those valid con­cern­s? Are there many more? Would you do it com­plete­ly dif­fer­en­t?

The book is open source, and avail­able at http://no­muerde.net­man­ager­s.­com.ar (In span­ish, sor­ry!)
