Problem: A large project has lots of apps, so naturally you want a twin column admin interface, with the history out beyond those two columns...

Solution: Involved editing the admin/index.html template, a simple modification to the adminapplist template tag, and a flag placed in each models.py for models you want in column two.

Instructions:

  1. Create the app templates/admin/index.html file by copying and pasting the provided code.
  2. Copy django/contrib/admin/templatetags/adminapplist.py to your app/templatetags directory as column_adminapplist.py and edit as shown in the provided code.
  3. add a _admin_index_column = 2 near the top of each models.py file for each one you want to be on the right hand side.

The next code is for a custom adminapplist.py
Copy django/contrib/admin/templatetags/adminapplist.py 
to your app/templatetags/ directory as column_adminapplist.py
and edit in two places as below:
##############################
# After   has_module_perms = user.has_module_perms(app_label)
# Before  if has_module_perms:
# Paste these four lines into the context (indenting them appropriately):
if hasattr(app, '_admin_index_column'):
    index_column = app._admin_index_column
else:
    index_column = 1
# And in app_list.append({<stuff>}) add
'column': index_column,
# to the dict options.
