What is the enhancement in mind? How should it look and feel?

Add a highlight option to allow highlighting of items based on conditions
Conditions should be similar to current bag categories but should not make new categories but just highlight items within the current categories

Please provide any additional information below.
Different highlights are required EG Colored Border and or Shaded Item (such as non-search match look)
Examples of useful highlight conditions- the use - and a suggested highlight

Soul Bound and Trade Window  - Only can be dragged to "NoTrade" slot - Yellow border
Soul Bound and Mail/AH/GuildBank Window  - Cannot be sent - Grey entire box
Soul Bound and Vendor  - Maybe sold if not a useful item - Green Border
In Bank and In Bag - Useful combing stacks between bank and bags - Green Border (would be nice to auto select colors so they each item gets a different color)
Unsellable and Vendor - cant sell - Grey item
Timeditems - items which will expire at some time - clock icon over lay

Items which can be combined (eg more than 10 motes of ....) - allow combine - border
Disenchanted - based on your level - DE Icon overlay
Openable items (although I have requested Autobar do this as well) - allow open - Lock
Items which can start quests - start quest - ! icon
Turnin only (Eg Marks of Honor Hold) - ignore unless at vendor - grey
