The noticeable new features are the drop shadow and the size and color options.
For the X10 this was the best configuration that would use a good portion of the screen without getting parts of the widget getting clipped. You CAN select 1.4 for the widget size but if you are going to use a drop shadow the shadow will get clipped at the bottom of the widget.
If you like me and feel asleep in html class and forgot about hex color codes then heres a site to help you out. HEX COLORS
I just released this last Wednesday, that when you set the size above 1.2 Wednesday gets clipped off. So I guess the best fit is 1.2, not a big difference but its better than 1.0 lol. I wish if there was a set x set y feature for the app.
Hope it Helps
