Sugar 7 : how to disable "create lead" button in Main Menu?

Question

Hello everyone,
Here i come again with a new problem/question !

Sugar 7.2.0, Pro edition :
My Leads are automatically created (by .csv imports or by another way), and I would like to disable the standard creation for all users.

My question could be cut in two parts :
- How do I disable the "Create a Lead" button in the module tab's dropdown on the Main Menu?
( tried to disable it via custom/modules/Leads/clients/base/views/headerpane/headerpane.php, ran QRR, but did nothing)
- How do I disable the "Create" button in the Leads' ListView?
(i checked out custom/modules/Leads/clients/base/views/list/list.php and there is nothing about buttons)
- How do i disable every create leads button, in all the application, in fact?

Thanks a lot for giving me clues on where i should search :)

Sorry I was unclear as usual In my case it was for a custom module and I created modules/zz_expenses_detail/clients/base/views/list-headerpane/list-headerpane.php I havent tested it but I'm pretty certain for leads you could create it in custom/modules/leads/.... my code is $viewdefs['zz_expenses_detail']['base']['view']['list-headerpane'] = array( 'template' => 'headerpane', 'title' => 'LBL_MODULE_NAME', 'buttons' => array( array( 'name' => 'sidebar_toggle', 'type' => 'sidebartoggle', ), ), );
