disabling/removing default sidebar links

[omnidan]

is it possible to remove the default sidebar link of a collection? I would like to disable the "new" submenu in the sidebar as I've already disabled it in the table, so my plan is to disable the default sidebar item and add a new, custom one without the submenu.

I would also like to be able to disable or hide the "New" link for some collections.

I don't want admins making any changes to particular collections (and allow only read-only access).

The showEditColumn and showDelColumn options in AdminConfig are OK (I set them to false) but there should also be an option for removing the ability to create a new entry.

What are the alternatives in the meantime?

CSS works:

a[href="/admin/Surveys/new"] {
  display: none !important;
}
