Version 1.4

This release comes with a new user interface. The buttons are now rounded and coloured to show grouping (replaces the underlying coloured rectangle). The font for the number keypad is bigger and the symbols are nicer. Power math function buttons now use superscript instead of the ^ symbol. You can see some more screenshots here.












Additionally, I implemented the two user suggestions mentioned in the Version 1.3.3 comment of this blog: the delta % function as well as a special keypad giving access to all hex numbers (0 to F) at once.
