Warehouse "Info" columns
 

Using DEV version (2.0) -- Warehouse. I'm wondering if those columns for "Info 2," and "Info 3" are temporary 'placeholders' for future use, or not. Once upon a time, I remember I could see links to "previously-visited vendors" for each of those items in one of those columns plus other helpful information. Will that return someday in the far future?

EDITED: I'm also wondering if they are related to the other two Carbonite modules "Carbonite Info 6.2.0" and "Carbonite Items 6.2.0"?
** Can I remove these 2 modules from my character's Addon list(s) safely (without causing issues with other Carbonite modules)?
