I want to customise modeladmin in 3.0.3+ doing the following:
1. allowing sitetree items to be working with proper "save and publish, etc..."
2. adding previous and next buttons, which will allow you to go from one detailed view to the next without having to fork back to the list view.
Here are a few ideas I had so far:
1. extend GridFieldDetailForm and override some of the methods there (i.e. ItemEditForm)
2. in extending module admin I set a slightly different set of options for the GridField, adding MyGridFieldDetailForm
Do you have any sample code or ideas on this?
