I have filed this as:
As a side note, how did you discover you could do this, just by looking at the source, or was there some documentation somewhere that discussed this? As I don't see anything in the admin console.
Source code search for "status" turned up this servlet. Looking at the code, it seemed like this was the intent of the functionality. In general, the request is more towards providing a way to customize the status icons / add new ones etc..whether it is with this servlet or not...I am indifferent. =)
How did you copy your files to the /resources/images/status directories?
