Comment on PEMDAS

I just saw this, ive been using Calc (http://osx.iusethis.com/app/calc) which is similar. However this app does look more beautiful.

I have one request tho, the ability to resize the application more, for most of my calculations i dont need 515 pixels wide textarea, i would love to resize it down to like 200px.

Thanks for making this app, looks great so far!
