Hello Louise,

I've pasted a diff below for the file ~/lib/galaxy/web/controller/admin.py that will provide what you want, I believe.  I didn't have time to fully test, but it gives you the idea.  You can make things prettier by wrapping the returned value in galaxy.datatypes.data.nice_size

Hello

I would like to add a column in the admin panel's user list with the sum of the file size of every dataset in each user's histories that don't belong to any ibrary.

Is there a way to do that?

I had a look at lib/galaxy/web/controller/admin.py and templates/grid_base.mako but I fail to see where the "query" variable (containing the items, therefore the users) come from in the mako template, so I didn't figure out what each column class in admin.py actually manipulates in the get_value() methods.

Regards,
L-A
