Some suggestions:
In the Send Money menu, any field where an amount of bitcoins can be entered, please make these fields bigger so we can see at least 13 digits. Right now it's really annoying how I can only see around 3 or 4 while my amount is typically accurate down to a satoshi which means at least 9 digits..
Also when sending anonymous please give us the option to specify from which addresses we want to send the coins like we can under "Custom", and change it in both places to give us an option to select which address to spend from first if the amount is less than what the multiple selected addresses contain. (oh and show a tip that one can select more addresses by holding down ctrl)
One more is for Import/export, where you can click paper wallet and it displays the paper wallet for all your addresses and their private keys.. a warning would be nice that it's about to do that.
And one final suggestion: for entering the second password when it opens up the keyboard, wouldn't it make sense to disable the ability to just type the password and also always display the keys at random so a mouse or keyboard tracking malware can't get the password?
