Hi,

May I suggest to reduce a little the default size of the list font, 
and/or, make system windows a little bigger? I like the bigger fonts of 
3.9 but the 4 columns browsers are an usability pain. And if we are 
going to remove the horizontal scrollbars it will make that aspect a lot 
worse.

My 2 cents.

Regards,
Hernán
