Unfortunately, there is no way to increase the size of the icons or the text in the blue icon bar. But, all of the features in the icon bar are accessible from the  top grey menu, and most of them have keyboard shortcuts. Ex: 

CTRL+F = Find (Forms Icon)

Shift+F4 or Shift+Fn+F4 = Dependants

It does not help. When you're doing 50 or more returns per day, you can't afford additional keystrokes.
