VKB retains the ability to visually mark objects with background color and border width. Borders can be assigned a different color than background color.  Objects can also have transparency allowing objects to overlap but still be visible.

VKB has a history mechanism that records the evolution, local, global, and historical links for explicit navigational connections between chunks of information.

Background and Border Colors in VKB

VKB provides a slate of 12 modifiable color pallets that are stored for each space and easy to edit. In other systems, such as VIKI, the color pallets were for per user not per task and cumbersome to edit. 

VKB Color Pallets

JPEG and GIF image files are recognized and are able to be displayed at their full size or as thumbnails.  As objects they can have borders and backgrounds, or be used as backgrounds thus adding another color option.  This would allow objects to be organized by a common theme.  

Image use in VKB 

Files can be dragged and dropped into VKB allowing documents or images to be easily loaded.  They can be dragged into an existing object, or a new object will be created if there is not one already where the file is dragged. URLS can also be dragged into VKB. Though URLS will open a browser window when selected.
