I would like to suggest the option to color-code variable types in the preference menu. This might allow for quick distinction when viewing a large list of variables. The implementation might be (only a suggestion):

- ability to color the _font_ of non-object types -- string, boolean, integer, floating points, array, resources (1 color per type ie - red for boolean, green for string, etc )
- ability to color the _background_ of object type (1 color for all objects)
- ability to color the (background, i guess?) superglobals as distinct from object colorings.

Thanks in advance and keep up the great work!

Targeting for the 1.4 milestone.
