Security -> Manage Users: how to extend Grid columns?

is there a way how to do that?
we already have (id, Name, Full name, Email, Active, Blocked). I need some more columns like (phone, dob, etc).

and most important, how can I display the extended values (wich are stored in json format)?

thanks for any help

Good blog post on Extended User Fields and JSON:

Hi David,

thanks for replay.

i have tried to modify this one manager/assets/modext/widgets/security/mox.grid.user.js where actually the columns are. i just added 'phone' field to test if it works. the column was created but no value on it. the same with other fields like 'dob' or 'extended'.

any suggestions?

is someone here who can help me?
