This is just a visual for old GUI suggestions (...nothing more...).

The problems that I am listing, appear in many places.
I am picking the Proxy screen only because it shows several problems, all on one place.

• We scan down a page, find what we are looking for, and then start reading.
  This is harder for our eyes to scan down a screen, when text is butted up against labels or icons.
  
  
• Selecting an inputbox, causes its border to change to orange.
  But since the border is only 1 pixel wide, it is hard to see this.
  
  
• Even after you select an inputbox, the cursorbar is not shown.
  The cursor-bar appears only after you start typing or cursor'ing.
  
  
• The inputboxes are too small, and descending characters (like 'y' and 'p') get cut-off.
  
  
• There is no space between inputboxes; which makes it look like a menu, rather than an inputbox.
  And in this case, the lower box is covering part of the upper box.

To use CSS parlance, you need to add padding and margin commands.

P.S.: The refresh is working great. Thanks!
