Node switching can have unexpected results on some pages. E.g:

1. When switching a node from a host edit form, the user will be redirected to a different host from the new node;
2. When switching a node from a host create form, the user will be redirected to the list of hosts;
2. When switching a node from a list of LLD rules, the user will see a critical error.

I think the user should always be redirected to the current page from the sub menu, i.e. when editing hosts - to the list of hosts, when editing screens - to the list of screens, etc.
