I added a custom field called "Code Reviewer". I have it as a multi user picker field, but I also tried a regular user picker field. If I put them on the card or list view in Greenhopper, the don't work like the Assignee picker. Basically, if you now the users username you can type it in. Howerver, I was expecting it to have that auto complete dropdown that's in the assignee's field. On top of that when using the multi picker I'm not sure how you would specify more than one user.
I searched everywhere for somone else having this issue, but found nothing. Maybe it's just something dumb I'm doing. Please help.
