It would be interesting to be able to have bookmarks that are shared across all connections.
Add support for shared searches across all connections
I think we can regroup the two issue under a common preference page.
I think we could add a new preference page called 'Shared/Common Bookmarks', child of the 'LDAP Browser' preference page, where the user would be able to add/edit/remove these bookmarks.
In the 'Browser view', we could add another sort preference to group shared bookmarks together and appear before or after connection-specific bookmarks.
